Effect of thermal neutron irradiation on the electrophysical and photoelectric properties of Hg₀.₈Cd₀.₂Te crystals

Abstract

We have studied experimentally the effect of thermal neutron irradiation on the electrophysical and photoelectric parameters of Hg₁₋xCdxTe crystals. The irradiation was shown to produce both donor- and acceptor-type radiation defects. In this case the majority charge carrier mobility decreases significantly. An analysis is given of a model for radiation defect production. The photoconduction processes are explained from the standpoint of clusterization of such radiation defects.
