摘要：

We have examined Bridgman-grown zincblende CdSeTe1-x (x < 0.36) by Raman scattering, Fourier transform infrared reflectivity, photoluminescence and theoretical analysis. The Raman data showed evidence of surface structural improvement by long-term room temperature annealing. The combined Raman and infrared data confirmed the interpretation that a third infrared mode besides the CdTe- and CdSe-like transverse optical phonon modes, arose from non-random atomic clustering. Room temperature photoluminescence spectra were obtained and compared with pseudopotential calculations.
