Study of defects in CdTe: Cl by cathodoluminescence microscopy

The effect of Cl doping on the luminescence properties of CdTe is investigated by cathodoluminescence microscopy. Cl enhances the 1.4 eV emission and retards the appearance of the tellurium vacancy related emission band. The behaviour under annealing indicates that doping with substitutional impurities involved in A-centers influences the intensity of the 1.4 eV band
