Abstract
The presence of damage layers close to the interface of Schottky barriers causes local band distortion in this region. This band bending is shown, under certain conditions, to produce a current flow in the opposite sense to that usually expected during emission from trap levels in a Schottky barrier depletion layer. The influence of this anomalous current flow on thermally stimulated current and transient current measurements is discussed. It is shown that this can produce erroneous results from these techniques, and measurements on GaAs Schottky barriers are given as specific examples.
