摘要
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.
