  • Braiding Operations for a Topological Josephson Junction Array using SFQ Current Pulses

    Abstract

    Majorana bound states (MBSs) can occur in topological Josephson junction (JJ) arrays with the presence of a fractional vortex with 2π-phase winding. It has been theoretically shown that the braiding operation can be achieved by using current pulses, compatible with single flux quantum (SFQ) technology. Therefore, we designed an SFQ logic circuit for the braiding operations of the topological JJ array using single flux quanta in a conventional JJ array. Braiding operations could be realized by an SFQ logic circuit with double flux quantum driver. To obtain positive and negative current pulses using the SFQ logic circuit, we used SFQ logic circuits with ac biasing for simulation. Finally, we confirmed the CNOT operation using an array-type SFQ circuit by means of simulation and estimated the CNOT operation speed.

  • Josephson Effect and Charge Distribution in Thin Bi2Te3 Topological Insulators
    Martin P. Stehno; Prosper Ngabonziza; Hiroaki Myoren; Alexander Brinkman
    Advanced Materials, Volume:32, Number:14, Feb. 2020, [Reviewed]
    Abstract

    Thin layers of topological insulator materials are quasi‐2D systems featuring a complex interplay between quantum confinement and topological band structure. To understand the role of the spatial distribution of carriers in electrical transport, the Josephson effect, magnetotransport, and weak anti‐localization are studied in bottom‐gated thin Bi2Te3 topological insulator films. The experimental carrier densities are compared to a model based on the solutions of the self‐consistent Schrödinger–Poisson equations and they are in excellent agreement. The modeling allows for a quantitative interpretation of the weak antilocalization correction to the conduction and of the critical current of Josephson junctions with weak links made from such films without any ad hoc assumptions.

    Switching functions using a parallel connection of conventional-type and π-type junctions have been investigated. Both junctions consist of Nb/Au/YBa2Cu3O7−δ Josephson junctions on YBa2Cu3O7−δ edges, whose faces are (110) and (100). The modulation patterns of critical currents in low magnetic fields indicate that the d-wave component is dominant: the (100) junctions exhibit the conventional type, but the (110) junctions the π type. Superconducting current path is alternated between the conventional junction and the π junction by applied magnetic fields using these anisotropic magnetic field dependences of the critical current.

  • Mixing at terahertz frequency band using YBa2Cu3O7−δ bicrystal Josephson junctions

    Using high-Tc Josephson junctions made of YBa2Cu3O7−δ deposited across MgO bicrystal boundary, at terahertz (THz) frequency band, we demonstrated both fundamental and harmonic mixing. Radiation from a far-infrared laser was coupled to the junction, which was integrated with a planar bow-tie antenna, via an extended hyperhemispherical silicon lens. Fundamental mixing manifested itself in the junction’s dc current–voltage (I–V) curve as a third Shapiro step in addition to those two induced by the THz laser lines from a slightly misaligned resonator. In harmonic mixing between a THz laser line and a microwave local oscillator, the highest harmonic number we could get was 490 with a signal-to-noise ratio of 9 dB at the intermediate frequency.

  • Intrinsic noise temperatures of YBa2Cu3O7−δ Josephson devices on bicrystal substrates and the upper frequency limit for their operation

    Following a method proposed by Divin and Modovets [Sov. Tech. Phys. Lett. 9, 108 (1983)], we have measured at millimeter waveband the intrinsic noise temperatures TN of YBa2Cu3O7−δ Josephson junctions or dc superconducting quantum interference devices (SQUIDs) fabricated on SrTiO3, yttria-stabilized ZrO2, or Si bicrystal substrates. Over wide ranges of physical temperatures TP and the junction’s normal resistance RN, it was found that TN follows TP pretty well. This indicates that the intrinsic noise in the devices is dominated by Johnson noise. TN was also measured in cases where there is external magnetic field applied, or where there is another microwave radiation like the local oscillator in a mixer. The magnetic field or microwave radiation does not seem to affect TN in any appreciable way. To estimate the high frequency performance of the junctions on Si bicrystal substrates, direct irradiation by a far infrared laser at 1.81 THz is carried out and the clear first Shapiro step is observed.

    We have studied low frequency (1/f) noise of YBa2Cu3O7−δ dc superconducting quantum interference devices (SQUIDs) on SrTiO3 bicrystal substrates. 1/f flux noise, either measured at different temperatures for optimized bias current or measured at 77 K for different bias currents, is almost constant. These facts imply that 1/f noise mainly comes from fluctuations of the critical current of the Josephson junction that form the SQUID. Also, we explain the critical current fluctuations in the junction by an equilibrium temperature fluctuation model.

    Various effects of the electric field on YBa2Cu3O7-δ grain boundary Josephson junctions were studied using inverted metal-insulator-superconductor (MIS) samples which employed bicrystal SrTiO3 substrates as insulators. The critical cutrents, I c of the junctions were regulated by gate voltages with the field-induced changes in charge carrier densities. Furthermore, a significant field effect on equidistant step structures observed in I-V curves was found. The equidistant steps can be ascribed to self-resonances of the ac Josephson current in the grain boundary junctions. The gate voltages shifted the step voltages corresponding to resonance frequencies of the grain boundary toward high voltages. This appears to be a consequence of the field dependence of dielectric properties of grain boundary junctions.

  • Electric field effect on the artificial grain boundary of bicrystal YBa2Cu3O7−δ films

    An ability of the artificial grain boundary of bicrystal YBa2Cu3O7−δ thin films is demonstrated as the field effect channel of high Tc field effect devices. The influence of field application on the channel resistance is examined with a metal-insulator-semiconductor-type structure, in which a channel is arranged across the grain boundary. The field-induced change in the resistance of the grain boundary is enhanced up to around 5% by lowering temperature below Tc of adjoining YBa2Cu3O7−δ grains. The enhancement is explained not only by an increase in the dielectric constant of the gate insulator (SrTiO3) but also by a reduction in the carrier density nearby the grain boundary. The latter is indeed a benefit to high Tc field effect devices.

    The dielectric properties in the infrared region of SrTiO3 thin film on Pd/Si were studied using reflectance spectra of radiation polarized parallel to the incident plane. The absorption bands of LO (optical phonon) modes increase linearly with increasing incident angle. Maximum sensitivity can be obtained using an incident angle of about 60∼85°. There is sufficient sensitivity at the film thickness of less than 10 nm. These results suggest that p-polarized reflection spectroscopy is a promising technique for estimating dielectric properties for very thin SrTiO3 films on metal/Si.

    We report the observation of an efficient visible photoluminescence (PL) from Si microcrystals embedded in SiO2 glass films. The Si microcrystals were formed by the rf magnetron sputtering technique. The peak position of the PL spectra at 77 K shifts to a lower-energy side as the average diameter of the Si microcrystals increases.

    Ultrathin Ba2YCu3O x films with thickness down to 7 nm were grown epitaxially on a Si(100) substrate using buffer layers (Y2O3(10 nm) and YSZ(40 nm)). These films show metallic behavior and full superconductivity through revealing broadened transitions. The critical current densities at 40 K are about 5×106 A/cm2 and 5×105 A/cm2 for 100 nm- and 28 nm-thick films, respectively.

In addition to the published results on YBa2Cu3O x and Tl2Ba2CaCu2O x , the present measurement suggests that nonlinear I-V characteristics of high-T c superconductors are universal and in agreement with a theoretical prediction based on a three-dimensional superconducting “vortex-glass” phase.

    Si bicrystal substrates with angle grain boundaries (AGB) have been fabricated for the first time by a diffusion bonding technique using the hot-press method. YBa2Cu3O7-δ (YBCO) epitaxial thin films are grown on the Si bicrystal substrates with yttria (Y2O3) and yttria-stabilized zirconia (YSZ) buffer layers by rf magnetron sputtering. The properties of bridge-type junctions patterned by excimer laser have been studied from 4.2 K to 77 K and by microwave irradiation. It is found that the critical current density of the AGB junction (J c A) is always less than that of either bridge made on single-crystal grains (J c G). The effects of the temperature and microwave radiation show that the properties of the bridges on the grains are limited by flux creep. In contrast, the properties of the AGB junction with the angle larger than 10° show the Josephson effect.

  • Fabrication of All-High-Tc Josephson Junction Using As-Grown YBa2Cu3Ox Thin Films
    Kanji Harada; Hiroaki Myoren; Yukio Osaka
    Japanese Journal of Applied Physics, Volume:30, Number:8A, First page:L1387, Last page:L1387, Aug. 1991, [Reviewed]
    All-high-T c Josephson junctions consisting of a YBCO/barrier/YBCO-layered structure using epitaxial YBCO films sputtered on MgO(100) have been successfully fabricated. The barrier layer was obtained by Ar+O2 plasma treatment of the surface of the base electrodes. These junctions show superconductor/normal-metal/superconductor (SNS)-like current-voltage characteristics. Constant-voltage current steps observed in response to 10 GHz microwave radiation show that ac-Josephson effects occur in these junctions.

    As-grown Ba2YCu3O x thin films (\lesssim100 nm) have been prepared by rf magnetron sputtering deposited on Si(100) with buffer layers of YSZ and Y2O3/YSZ. Epitaxial growth of Ba2YCu3O x thin films is confirmed by ion channeling measurements along the (100) directions of the Si substrate showing a χmin of 60% on YSZ/Si, and 6% on Y2O3/YSZ/Si using 2.0 MeV He+. The as-grown films have critical current densities of 104 A/cm2 on YSZ/Si and 106 A/cm2 on Y2O3/YSZ/Si at 77 K. Our results indicate that the superconducting properties of the films are limited primarily by the value of lattice mismatch between the Ba2YCu3O x and buffer layers.

  • Josephson Effect in Wide Superconducting Bridges Made by Epitaxial Ba2YCu3Ox Thin Films on YSZ/Si(100)

    Japanese Journal of Applied Physics, Volume:28, Number:12A, First page:L2213, Last page:L2213, Dec. 1989, [Reviewed]
    Using the silicon substrates patterned with the trench, the superconducting microbridge junction has been fabricated in as-grown Ba2YCu3O x thin films by rf magnetron sputtering. The microbridge junctions with constrictions as small as submicron dimensions were obtained. These microbridge junctions behaved as Josephson junctions and microwave-induced steps were observed. The observed characteristics seem to be consistent with those expected for a homogeneous wide superconducting bridge (constriction size≫coherence length).

  • Bond-Angle Distribution of Sn Atom and 119Sn Mössbauer Spectroscopy in Hydrogenated Amorphous Silicon Doped by Sn
    Hiroaki Myoren; Yukio Osaka
    Japanese Journal of Applied Physics, Volume:28, Number:7R, First page:1165, Last page:1165, Jul. 1989, [Reviewed]
    The 119Sn Mössbauer spectral shape resulting from the bond-angle distribution of a Sn atom in a Si matrix is theoretically investigated. The application of this theory to the experiments on 119Sn Mössbauer spectroscopy of sputtered a-Si:H films shows that the generation of fewer overconstrained regions due to SiH2 bonding configuration appreciably decreases the standard deviation σ of the bond angle deviation for the Sn atom. For sputtered a-Si:H films, the minimum value of σ is estimated to be 2.6°, which is mach smaller than the σ (≃7.7°) for the unhydrogenated films.

  • As-Grown Preparation of Superconducting Epitaxial Ba2YCu3Ox Thin Films Sputtered on Epitaxially Grown ZrO2/Si(100)

    High-T c superconducting Ba2YCu3O x thin films have been epitaxially grown on Si(100) substrates with the epitaxially grown tetragonal ZrO2 or cubic yttria-stabilized zirconia (YSZ) as a buffer layer. The thin films were prepared by rf magnetron sputtering of the stoichiometric Ba2YCu3O x target below 700°C. An adequate positive substrate bias was necessary to ensure surface smoothness and to show the superconducting transition above liquid nitrogen temperature without any post-treatment. The highest T c(onset) and T c(end) observed were 88 K and 84 K, respectively.

  • Synthesis of Metastable GexSn1-x Alloys by Chemical Sputtering in H2

    Japanese Journal of Applied Physics, Volume:28, Number:1A, First page:L125, Last page:L125, Jan. 1989, [Reviewed]
    Thin films of metastable alloy Ge x Sn1-x (0≦x≦1) are formed by chemical sputtering in H2 on glass and semiconducting crystalline substrates. X-ray diffraction indicates the formation of microcrystalline Ge x Sn1-x alloy films with a diamond structure. Ge x Sn1-x films deposited on InSb(x=0) and GaSb(x=0.47) substrates with lattice matches consist of polycrystals and are shown to have a crystal orientation nearly aligned to the substrate by RHEED observations. The chemical sputtering technique is appropriate for synthesizing Ge x Sn1-x alloys which might have potential as direct and narrow band gap materials.

  • Structural Changes of Amorphous Ge1-xSnx Alloy Films by Annealing

    Microcrystalline (µc-) grains of Ge1-y Sn y (0.1<y<0.4) were precipitated by thermal treatments of amorphous films of a Ge1-x Sn x (x<0.4) alloy deposited by co-sputtering. At higher temperatures grains of β-Sn came out, co-existing with those of µc-Ge1-y Sn y . Mössbauer spectroscopy was used to characterize states of Sn in a Ge-Sn alloy film. Optical properties, such as the real part ε 1 of the complex dielectric constant for Ge0.65Sn0.35, also changed as the structure change, especially at a photon energy of 1.6∼1.8 eV, where ε 1 took a maximum. It was suggested that an amorphous Ge-Sn alloy might be a good material for archival-type optical storage.

    We propose a high spatial resolution gamma ray camera with superconducting resonator arrays for food screening systems. The gamma ray camera is composed of hundreds of microwave resonators. Absorbers are attached to the reverse side of the wafer. The gamma-rays create phonons in the absorber and the resonators detect the phonons propagated from the absorber. As a first step for the proposed camera, we measured 10 lumped element kinetic inductance detectors (LeKIDs) in a 0.3-K sorption cryostat. The event rate of the pixel with the Pb absorber was approximately 5 cps and 6 times higher than that of the pixel without the absorber. The rise and the fall time of events were less than the 1.1 MHz sampling of a vector network analyzer.

    Superconducting nanowire single photon detectors (SNSPDs), those have a low dark count rate characteristics, fast and low jittering response, and high quantum efficiency, are expected to be used in the quantum information field and time-of-flight (TOF) mass spectrometry etc. A readout circuit using superconducting single-flux-quantum (SFQ) logic circuits has been developed to realize fast and low-jittering readout for an array of SNSPDs. SNSPDs with series-parallel meander type configurations have been demonstrated to have photon number resolving capabilities and are expected to be used for an evaluation system of single photon generators and/or an energy-dissolved fast detector for new generation TOF mass spectrometry. In this study, we present design, fabrication and confirmation of correct operations of an SFQ digital readout circuit for an SNSPD with series-parallel meander type configuration.

    We have been developing terahertz cameras using superconducting micro-resonator arrays operated at 4K. A superconducting micro resonator, called Microwave Kinetic Inductance Detector(MKID), is one of the most sensitive detectors for terahertz wave. MKID is made from a Niobium Nitride films whose superconducting transition temperature is 15.7K with the thickness of 150nm. The film is deposited on an MgO substrate by magnetron sputtering method. To increase the number of detectors per area, we estimate the amount of microwave crosstalk between pixels with Ansys Designer. We find that the pixel crosstalk occurs by both inductive and capacitive coupling.

    Terahertz electromagnetic waves (THz waves) are very attractive features for various fields such as engineering, medical and sciences. We have developed superconducting tunnel junctions (STJs) for THz waves detector. Our proposed detectors utilize a substrate of the STJ. This is called phonon-mediated method. In this paper, we introduce the results of STJ for THz waves detector with phonon-mediate method.

    We have designed and fabricated sub-micron-wide microstrip lines (MSLs) for SFQ circuits. We adopted Al_2O_3 as the insulator of MSLs to realize characteristic impedance of 10 Ω which is equivalent to one of future SFQ VLSI circuits. To evaluate propagation characteristics of MSLs, we measured loaded quality factors of resonance QL. In this measurement, we obtained fundamental resonance peaks around 6 GHz against a design value 5 GHz for each MSL and respective QL is about 100.
    For the high-density SFQ VLSI circuits, three-dimensional (3-D) integration will be needed. We are trying an Nb electrodeposition from non-aqueous electrolytes, which is suitable for making 3-D wiring through substrates. For the Nb electrodeposition from non-aqueous electrolytes, relatively smooth, metallic colored Nb compound films were obtained from solutions containing LiNbCl_6.

    We investigated superconducting NbN nanowire as a photo switch for generating single flux quantum (SFQ) pulses.
    Epitaxially grown NbN thin films were prepared on MgO (100) substrates by a dc magnetron sputtering method using gas mixture of Ar + N_2, without substrate heating. NbN thin films showed Tc of 14K for 8 nm, and 10K for 4 nm.
    NbN nanowires were patterned using a electron direct drawing method with 200 nm thick electron resist. To increasing photo-sensitive regions, we fabricated 50 x 50 μm^2 meander patterns with NbN nanowires. Line width of nanowires was varied from 200 nm to 500 nm. Critical current density of NbN nanowires was about 3x10^6A/cm^2 at 4.2 K.
    We irradiated 850-nm laser pulses via 50-mm multi-mode optical fibers. Repetition frequency and pulse width could be controlled by a pulse pattern generator. The maximum laser pulse power was about 1 mW. Using 200-nm-wide NbN nanowires, one third of critical current was suppressed by 1 mW CW laser irradiations. High speed responses were observed for laser pulses with repetition frequency of 1MHz and pulse width of 2 ns.
    On the other hand, we designed an SFQ generation circuit using Josephson transmission lines assuming NbN nanowire switch generates 60 μA current pulses. The designed circuit could generate SFQ pulses by 10 μA, 25 GHz current pulses. Dc bias margin of the circuit was +- 15% for 60 μA current pulses.

    On-chip double relaxation oscillation SQUID(DROS) with a superconducting digital flux locked-loop(FLL) circuit is demonstrated far high sensitive magnetic flux sensor and SQUID amplifier. In this study, we examined two kinds of superconducting digital FLL circuits : one was composed of a 8-bit up/down counter and a 8-bit R-2R ladder-type D/A converter designed using 4JL-gates which are driven by a two phase power supply at a frequency up to 4GHz. The other one was composed of an on-chip FLL circuit based on a Josephson counter and a 6-bit up/down counter using SFQ logic gates.
    In the up/down counter, we used binary carry lookahead(BCL) circuits for high-speed operation. Logic simulations for the 4JL 8-bit up/down counter with BCL circuits showed correct up-and down-counting operation at 4GHz clock frequency assuming a 2.5kA/cm^2 Nb/Al-AlO_x/Nb junction technology. We expected that a DROS with the superconducting digital FLL circuit has large slew rate as high as 10-7Φ_0/s.
    Using the 6-bit up/down counter using SFQ logic gates, logic simulations showed the correct up and down counting operation up to 33GHz and we expected that a DROS with the SFQ digital FLL circuits can be operated at 10GHz.

    We prepared Nb_<1-x>Ti_xN (NbTiN) thin films by reactive do magnetron sputtering without intentional heating. Superconducting properties were strongly related to sputtering conditions. Lattice parameters of NbTiN films approached that of bulk NbTiN with decreasing the N_2 mole fraction in Ar and N_2 sputtering gas mixture. The film orientation was also strongly related with the sputtering conditions such as gas pressure. NbN thin films could grow epitaxially on MgO(100) substrates and showed very smooth surfaces. We found that smooth NbTiN films could be obtained on MgO(100) substrates with epitaxially grown NbN template layer. Superconducting critical temperature of NbTiN films were up to 14.5 K.
    We prepared AlN thin films for tunnel barriers and found that smooth AlN thin layers could be obtained by reactive dc magnetron sputtering with relatively small sputtering power of 50 W. Etching rate of AlN layers was decreased with increasing CF_4 gas pressure and AlN layer could behave as a etching stopping layer. We fabricated NbTiN/AlN/NbTiN tunnel structure and observed I-V curves with the superoonducting energy-gap structure.
    We successfully designed and fabricated single flux quantum (SFQ) NAND and NOR gates. We designed mask layouts of the gates assuming a 2.5 kA/cm^2 Nb/AlO_x/Nb junction process and optimized device parameters using an SFQ circuit-optimizing tool. Fabricated NAND and NOR gates had a critical margin more than ±20% for low-frequency operation. Bias margin for a fabricated NAND gate exceed ±25%.

    It is expected that high Tc superconducting millimeter and submillimeter wave devices such as a low loss transmission line and a high sensitivity detector, which can be operated with a simple cryogenic system, are applicable for a ultra high speed communication system in order to supply a communication demand. Specific high frequency properties of high T_C superconductors caused by the characteristic layred structure is also attractive from the application point of view. In this research project we aimed to develop fundamental technologies of electromagnetic wave detectors for millimeter and submillimeter bands using high T_C superconducting YBCO grain boundary Josephson junctions (GBJJ) on silicon bicrystal substrates. We have first succeeded a video detection of 2.525THz signal using YBCO GBJJs operated at 70K as a result of improvements of junction parameters such as the supercondcuting transition temperature, Tc and the I_CR_N product. Furthermore, we found that high frequency response (Shapiro step) was enhanced by a weak magnetic field application for wide frequency range up to submillimeter wave through microwave. This is a quite useful knowledge to develop a practical submillimater wave spectrometer using the GBJJ.Harmonic heterodyne mixing experiments were also performed using GBJJ for a submillimeter signal of f_S=2.525THz and a microwave signal of f_=19.4176268GHz then we had 130th harmonic mixing output {IF (Intermediate Frequency) output}. For the harmonic mixing we had the signal and noise ratio (S/N) of about 20dB and the spectrum resolution of 100KHz. The S/N would be improved to some extent by optimizing high frequency circuit design. In conclusion we have substantiated that the harmonic heterodyne mixing using GBJJs performs the high spectrum resolution for millimater and submillimeter waves and a precise spectrometer for the entire frequency range will be practical together with the video detection.

    Field effects of High-T_c Oxide Superconductors expected from their characterisctics of low carrier densities and short coherent lengths are hopefully applicable to superconducting three terminal devices. To achieve actual devices, however, a lot of difficulties, i. e fabrication of high quality ultra thin ETSC films with the thickness of several nm and development of insulating layr with a large dielectric constant still remains. From the another point of view, tilt grain boundaries not only behave as Josephson junctions but also have a large field sensitiviy because of local deficiency of charge carriers due to oxygen deficiency in the boundaries.
    In this research, we have investigated the electric field effects on artificial grain boundaries of YBCO films and obtained following results.
    ・The carrier density of the grain boundary was evaluated to be 2-5*10^<20>cm^<-3> from the measurement of the electric field effect on a normal conducting artificial grain boundary adjoining two superconducting YBCO grains. The carrier density was one drder lower than that in inner grains so that large electric field effects were expected. This is the first result indicating the usefulness of grain boudaries as field effect channels.
    ・As electric field effects with respect to AC and DC Josephson effects on the grain boundaries behaving as Josephson junctions, electric field modulations of both critical current, I_c and self resonance frequency were observed. For former effect, it was shown that the field effect in I_c was qualititavely explained by a charge carrier modulation in grain boundary junctions on the basis of the SNS model. For later one, the variations of the resonance frequencies were attributed to changes in the effective dielectric constants, epsilon^GB_/d reflecting the field strength dependence ofthe dielectric constant of STO used as substrates. The electric field modulation of epsilon^GB_/d is possibly applicable to the phase velocity control of electromagnetic waves transmitting in the grain boundaries in the case of Flux Flow Oscilator (FFO).
