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.
