Abstract

Uncooled photoelectromagnetic detectors (PEM-detector) on the basis of cadmium - mercury telluride solid solutions of composition x < 0.2 find application in opto-electronic systems with use of the C0₂-laser radiation with wave-length of 10.6 μM. [1] To advantages of such detectors it is possible to attribute absence of an external electric supply that reduces a level of noise and considerably reduces thermal loading on photodetector as well as it is a high speed responsivity that allows to use them in heterodyne systems of registration. The theoretical calculations of parameters of PEM detector has been carried out and results of development and research of uncooled PEM-detector on basis of Cd_xHg_1-xTe with x=0.2 of 6÷7 μm range of spectrum are represented by us in paper [2]. At the heart of work the researches of parameters of the PEM detector depending on a level of acceptor doping of the semiconductor have been discounted. In the present work the results of research of an opportunity of increasing of parameters of the PEM detector on basis of Cd_xHg_1-xTe with x = 0.167 corresponding to a maximum of spectral sensitivity on wave-length of 10.6 μm at room temperature are represented.
