A new measurement technique that directly reveals the extent of the gate depletion region in FETs by using floating Schottky gates as potential probes is presented. Measurements on GaN heterojunction field heterojunction field effect transistors (HFETs) show that large extension of the depletion width is responsible for the high dc breakdown voltages in these HFETs.
