This paper presents a new ?-Ga2O3 Junctionless double gate Metal-Oxide-Field-Semiconductor-Effect-Transistor (?DG-JL-FET) with an embedded P+ packet at the oxide layer (PO-?DG-JL-FET) for high-frequency applications. Our goal is to achieve efficient volume depletion region by placing of silicon. We show that proposed structure has subthreshold swing ? 64 mV/decade. It suppressed band-to-band tu...
