摘要：

We report on a study of the experimental reflectance-difference (RD) line shape for CdTe near the E-1 and E-1 + Delta(1) spectral regions. A clear reflectivity component, as a major contribution near the E-1 and E-1 + Delta(1) spectral regions, to the measured RD CdTe line shape is found. No derivative-like, epsilon-like or 1/epsilon-like line shapes are observed for our sample. Results suggest that the experimental RD spectra cannot be explained by considering an anisotropic film on the surface of the material nor by a dislocation-induced piezo-optic effect.
