摘要：
Spectroscopic ellipsomerty measurements of the complex dielectric function of the CdTe thin films grown on GaAs(100) substrates by hot wall epitaxy have been performed in 1.5-5.5 eV photon energy range at room temperature. The spectroscopic ellipsometer spectra revealed distinct structures at energies of the E-1,E-1 + Delta(1)and E-2 critical points. These energies were decreased with increasing thickness of CdTe thin films.
