Abstract

Cathodoluminescence (CL) in the scanning electron microscope (SEM) has been used to investigate the effect of doping with chromium and vanadium on the native accepters and on the general structure of extended defects of gallium antimonide single crystals. Both impurities cause the reduction of the CL band at 775 meV (band A) attributed to a native acceptor. This effect is explained by the formation of a complex involving the dopant. CL images reveal the presence of precipitates and inhomogeneities in impurity distribution.
