High temperature (400/spl deg/C) performance of ohmic contacts to n-type GaN and GaAs

Stable high temperature ohmic contacts to III-V semiconductor materials are still rather problematic. In this work we report results on thermodynamically stable ohmic contacts to n-type Ga-V semiconductor materials (e.g., GaN and GaAs) that are capable of withstanding prolonged 400/spl deg/C exposure in untreated air ambient.
