摘要：
CdTe and (Cd,Zn)Te crystals were compared by their material properties. The compensation mechanism of(Cd,Zn)Te and the influence of deep levels are compared to CdTe. The detector grade of(Cd,Zn)Te is obtained with a peak-to-valley ratio of 3.5 for a Co-57 spectrum. The homogeneity of electrical properties is discussed by photoluminescence and TDCM mappings. Recent applications of(Cd,Zn)Te detectors are presented. (C) 1999 Elsevier Science B.V. All rights reserved.
