In this letter, the effect of Ge diffusion at the gate area of AlxGa1-xN/GaN high electron mobility transistors (HEMTs) on a thin silicon-on-insulator (SOI) substrate has been investigated. The pinch-off voltage shifted toward enhancement mode type operation behavior due to the Ge diffusion through...
