Abstract

The homogeneity and luminescence properties of undoped and Te-doped In _xGa_1-xSb crystals grown by the Bridgman and Vertical Feeding methods have been studied by cathodoluminescence (CL) and X-ray microanalysis in a scanning electron microscope. CL micrographs reveal the presence of non-radiative grain boundaries and dislocations in the investigated samples. Annealing at 650°C for 36 h significantly improves the structural quality and the compositional homogeneity of the Te-doped crystals. CL spectra of the ternary alloy were found to show features similar to those reported for GaSb.
