| dc.description.abstract | Cathodoluminescence in the scanning electron microscope has been used to investigate the effect of plastic deformation, produced by indentation, in Te-doped GaSb crystals. Deformation has been found to cause a strong quenching of the luminescence emission as well as spectral changes. In particular, the decrease of the near band edge emission is accompanied by the relative increase of the defect band A and of the 730 meV band related to the VGaGaSbTesb centres. Annealing treatments up to 600 degreesC lead to partial recovery of the deformation induced defects, and reveal the existence of Te out-diffusion processes from the deformed areas. | |
