Influence of te concentration on the infrared cathodoluminescence of GaAs:Te wafers

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...

Description
Summary: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.
