比较了CdTe晶体和（Cd,Zn）Te晶体的材料性能。比较了（Cd,Zn）Te的补偿机制和深度水平对CdTe的影响。在Co-57光谱中，（Cd,Zn）Te的峰谷比为3.5。通过光致发光和TDCM映射讨论了其电性能的均匀性。介绍了（Cd,Zn）Te探测器的最新应用。(C) 1999 Elsevier Science B.V.版权所有
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.
