Is. Virt et Is. Dutsyak, DEFECT FORMATION IN THE SURFACE-LAYER OF ELECTRON-IRRADIATED AND ION-IRRADIATED HG1-XCDXTE CRYSTALS, Inorganic materials, 33(11), 1997, pp. 1134-1137
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.
