Abstract
Photoconductivity transients have been measured in Cd1-xMnxTe: Ga (x=0 .01) single crystals at low temperatures. The transients observed are strongly nonexponential. Their variations with photon flux and photon energy can be explained by a two-stage photoionization process of Ga-r elated defects. A model in which the defect traps two electrons in its ground state and one electron in the intermediate state accounts for most of the features of our data.
