To obtain high blocking voltages and low forward losses in power diode structures, a Schottky contact can be merged with a MIS contact or a pn-junction. In this configuration, the Schottky contact is responsible for a low forward threshold voltage an

We report the utilization of synthetic diamond grown by chemical-vapour-deposition (CVD) for use as metal-semiconductor field-effect-transistors (MESFETs). The lack of a shallow n-type donor means that diamond-based electronic devices are unipolar (p
