Abstract
Cathodoluminescence (CL) scanning electron microscopy has been used to investigate the nature and distribution of defects involved in the infrared emission of GaAs:Te wafers. Spectral and CL-contrast changes as a function of doping level have been found. Profiles of infrared CL intensity across the wafers show an inverted U shape.
