Abstract

GaSb single crystals with different Er concentrations have been studied by cathodoluminescence in the scanning electron microscope. Low Er doping has been found to reduce the concentration of native accepters. In crystals with higher Er concentrations, Er-Sb precipitates form and doping becomes less efficient in suppressing the accepters. In these samples intraionic Er luminescence is observed.
