Uncooled photoconductive (Cd,Hg)Te detectors for the 8 14 μm region
Abstract
The construction, fabrication and performance of (Cd,Hg)Te photoconductive detectors operating at room temperature is presented, together with the theory of such detectors and expressions for the detectivity, responsivity and output signal. The performance limits of these detectors have been estimated. Experimental data on the measurement of the essential parameters of uncooled (Cd,Hg)Te detectors operating at 10.6 μm are given. These experimental results have been compared with the theoretical predictions and are found to be in reasonable agreement. Some examples of practical applications of uncooled photoconductive (Cd,Hg)Te detectors are presented. As a result of our investigations the possibility has been shown of construction and fabrication of uncooled photoconductive (Cd,Hg)Te detectors operating in the 8-14 μm region.
