摘要

应用红外光电导谱研究半绝缘p型Zn0.04Cd0.96Te中的深能级，在温度从4.2到165K范围内，观察到了位于0.24，0.34，0.38，0.47，0.55和0.80eV处6个光电导响应峰.结合4.2K下光致发光谱的测量结果以及对ZnxCd1-xTe中深能级发光光谱、深能级瞬态谱等已有的研究结果，对这些响应峰对应的深能级特性进行了讨论.%The infrared photoconductivity spectroscopy has been employed to investigate the deep levels in semi-insulating p-type Zn0.04Cd0.96Te. At the temperature ranging between 4.2 and 165K, photoconductivity peaks at 0.24，0.34，0.38，0.47，0.55 and 0.80eV are observed. In conjunction with the photoluminescence measurement of the sample at 4.2K, the characteristics of the deep levels related to the photoconductivity peaks are discussed.
