Abstract:This work investigates the cumulative dose 60 Co gamma (γ) -ray irradiation effects on enhancement mode HEMT devices inheriting 3D -Electron and Hole Gases for dosimeter applications. The devices are irradiated through a 60 Co source and demonstrate the enhancement in the drain current metrics. To elucidate, the said devices were irradiated through different mechanisms and the Compton effect was investigated through contour plots via TCAD simulations. The degradation of Schottky Gate contact and insulator char… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
