Abstract
In this paper, the numerical design of a optimized quasi-vertical gallium nitride power Schottky diode for high power electronic applications is illustrated. Bevel oxide field plate was employed as a junction termination technique to enhance the breakdown voltage in reverse bias. It was found that a maximum breakdown voltage of 1995 V was obtained for a bevel width of 18 um and oxide thickness of 1.5 um. This diode with on-state resistance of 14mΩcm2 has a high power figure of merit of 274 MW/cm2.
