过去几年,对研制8～14微米范围内以本征方式工作的HgCdTe探测器给于了较多的注意。本文将提出在该波长范围内的一种新探测器的初步研制结果。这种探测器除利用单晶PbSnTe材料外在许多方面都类似于HgCdTe探测器。这些PbSnTe探测器以光伏方式工作,因此响应速度快,同时由于不需使用偏压电流,探测器所显出的1/f噪声特性就很低。这种探测器是探测8～14微
In the past few years, more attention has been given to the development of HgCdTe detectors operating in an intrinsic manner in the range of 8 to 14 microns. This article will present preliminary results of a new detector in this wavelength range. In addition to the use of single-crystal PbSnTe single-detector material in many ways similar to the HgCdTe detector. These PbSnTe detectors work in photovoltaic mode and therefore respond quickly and at the same time the detector exhibits low 1 / f noise characteristics since no bias current is required. This detector is to detect 8 ~ 14 micro
