Non-Equilibrium Operation of Long Wavelength HgCdTe Photo Voltaic Detectors for Higher Operating Temperature Applications

Abstract

Mercury cadmium telluride (HgCdTe) alloy is of great importance to infrared sensing, and much of the research and development work is carried out for cooled operations. At ambient temperatures, intrinsic carriers are dominant, resulting in high dark currents. This technical report describes ways to reduce intrinsic carriers in ambient temperatures and, in particular, addresses reducing minority carriers in non-equilibrium operation under reverse biases.
