Abstract
Defect formation during electron and ion irradiations of Hg1-xCdxTe cr ystals was characterized by galvanomagnetic and photoelectric measurem ents. Irradiation with low-energy electrons gives rise to impurity red istribution in the surface layer. B+ ion implantation leads to the for mation of acceptor centers, presumably mercury vacancies, with ionizat ion energies E-a1 similar or equal to 18 meV and E-a2 similar or equal to 25 meV. A change in the mechanism of nonequilibrium-carrier recomb ination may occur some distance from the top surface.
