近年发展的本征材料碲鎘汞三元合金已成为一种最广泛研究和熟知的半导体合金。用它制备探测器具有以下优点:(1)改变合金组分(x值)就可调整响应波长,这样就可在最有效波长上得到最大灵敏度;(2)工作温度较高,可大大节减致冷装置,使重量和体积缩小;(3)吸收系数大,可制成较薄的探测器,对于制备阵列比较容易。但这种材料的不足
In recent years, the development of the intrinsic material HgCdTe ternary alloy has become one of the most widely studied and well-known semiconductor alloys. Using it to prepare a detector has the following advantages: (1) Changing the alloy composition (x value) allows the response wavelength to be adjusted so that maximum sensitivity is achieved at the most effective wavelength; (2) Higher operating temperatures result in substantial savings Cold device, so that the weight and volume reduction; (3) absorption coefficient, can be made thinner detector, for the preparation of the array is relatively easy. But this material is not enough
