Paper Abstract

The main physical properties of the Hgl-xCdxTe alloys are presented with some special features (matching of bandgap and spin orbit energies). Experimental measurement of life-time have been made on THM crystal with low doping levels. It is concluded that the dominant recombination mechanism is radiative. Hgl-xCdxTe photodiodes are described operating at various wavelengths such as 1.3-1.55-2.3 µm. These PIN and APD detectors exhibit high performances (low dark current, high hole/ electron ionization coefficient ratio, high RoA product). The capability of using Hgl-xCdxTe material for emitting devices has been investigated. The electroluminescence effect in PN junction has produced emission lines at 1.35 - 1.52 and 2.5 µm with interesting narrow linewidths.
