WebJun 9, 2016 · In this paper, a normally-off AlGaN/GaN MIS-HEMT with improved threshold voltage (V TH) thermal stability is reported with investigations on its physical mechanism. The normally-off operation of the device is achieved from novel short argon plasma treatment (APT) prior to the fluorine plasma treatment (FPT) on Al 2 O 3 gate dielectrics. WebThe threshold voltage, commonly abbreviated as V th or V GS (th), of a field-effect transistor (FET) is the minimum gate-to-source voltage (V GS) that is needed to …
