材料选择对于提高探测器的成品率,是非常重要的,尤其对于研制多元探测器及大面积二维列阵更是如此。以往一般仅从材料的宏观结构、电学参数去考虑,而我们在实验中发现材料的光学特性、晶体缺陷等因素与探测器性能关系密切。本文主要报道这一实验结果,为 Material selection is very important to improve the yield of the detector, especially for the development of multi-detector and large-area two-dimensional array is even more so. In the past generally only from the macrostructure of the material, the electrical parameters to consider, and we found in the experiment optical properties of materials, crystal defects and other factors closely related to detector performance. This article mainly reports the result of this experiment
