摘要

The vibrational Raman spectra of cadmium manganese telluride (Cd_1-xMn_xTe, CMT) were investigated in the range of 100-400 cm^-1 at room temperature. The dominant peaks at 140 and 161 cm^-1 were identified as transverse optic (TO) mode and longitudinal optic (LO) mode of "CdTe-like", while the emission peak at 124 cm^-1 was attributed to Te precipitates. The Te precipitates in CMT crystals were further investigated by field scanning electron microscope (FSEM) and transmission electron microscopy (TEM) observations. The results showed that the Te precipitates were the monoclinic phase with cell parameters of a = 0.3104 nm, b = 0.789 nm, c = 0.4683 and β = 92.71°. The orientational relationship between Te precipitate and the matrix was determined to be (0 over(3, ̄) 1)_Te / / (over(2, ̄) 0 2)_CMT.
