    We have carried out the dielectric function analysis of SmHx(x=2.28, 2.42, 2.56, 2.57) films based on the room-temperature reflectance spectra for photon energies ranging form 0.05 to 6.5 eV. The analysis has been performed by using i) the model dielectric functions and ii) Kramers-Kronig analysis to obtain the real and imaginary parts of the dielectric constants in SmHx. The both approaches demonstrate that the interband transition energy shows a red shift of about 1 eV when H/Sm ratio is increased from 2.28 to 2.57, though the lattice constant remains almost unchanged.

  • Nonlocal electro-optic effect in semiconductor thin films

    Electroreflectance(ER) spectra of GaAs thin film/Al0.3Ga0.7As-substrate systems are investigated theoretically by taking into account the nonlocal effect caused by the presence of a crystal surf-ace. Calculations are carried out by following the previous work by DelSole but considering influence of film thickness and nonflat-band modulation of a static electric field. It is shown from thickness variation of ER spectra that the refractive indexes of the thin films are reduced by a factor of about 0.1 when the nonlocal effect is considered.
