ABSTRACT:
A semiconductor material structure includes at least one region capable of generating electrons and holes each having an associated mean kinetic energy during operation. A material layer in proximity to the region provides an associated potential energy larger than the mean kinetic energy associated with the generated electrons and the mean kinetic energy associated with the holes.
