| Abstract: | Micron-scale Te-rich particles presented in CdZnTe crystals were directly observed using infrared transmission microscopy(IRTM).The generation of various Te-rich particles was discussed in conjunction with the growth conditions.In order to evaluate the impurities and defects behaviors,and to examine the crystalline quality,photoluminescence(PL) spectra were obtained at 10 K.The corresponding resistivity was evaluated simultaneously.The correlation between different shaped Te-rich particles in CdZnTe crystal... |
