Cathodoluminescence study of the radiative recombination properties of Se-doped GaSb crystals

The radiative recombination properties of Se-doped GaSb crystals grown by the Bridgman method have been investigated by cathodoluminescence (CL) microscopy and spectroscopy in the scanning electron microscope. A CL band centered at about 765 meV, not previously observed in undoped GaSb, is generally...
