Abstract:The paper analyze Raman and photoluminescence spectroscopy to CdZnTe(111) annealing.The firstly,in Raman,we measures CZT's Raman spectra in anti Stokes.One of spectra peak is transverse optical phonon (TO) at -125 cm -1 ,the another is longitudinal optical phonon (LO) at -142 cm -1 .The secondly,after same crystal was circumvolved,the LO/TO ratio is equal (111) isometric line.The third,its PL spectra of peak is at 807 nm (1.535 eV) and FWHM is 30 nm (0.057 eV).Circumvolved direction not change to PL spectra.Therefore,we need notice situation of crystal plane of CZT subtract,when HgCdTe single crystallinity film was grown.
