Abstract
High current gain InGaN base heterojunction bipolar transistors (HBTs) with a graded emitter design are presented. The devices show incremental current gain values above 30, and low offset and knee voltages of approximately 2-3 and 5-6 V, respectively. Device operation was demonstrated at temperatures as high as 300/spl deg/C.
