Studies of CdHgTe as a material for x- and g-ray detectors

Abstract

Optical, electric and photoelectric properties of Cd 1-x Hg x Te alloy with a low Hg content (x = 0.05) have been studied. The depth of impurity levels determining the conductivity of the material, their concentration and compensation degree, as well as the carrier lifetime and surface-recombination velocity have been found.
