High-Temperature Operation of Normally Off-Mode AlGaN/GaN Heterostructure Field-Effect Transistors with p-GaN Gate

Abstract
We demonstrated the high-temperature operation of normally off-mode heterostructure field-effect transistors (HFETs) with a p-GaN gate. The HFETs with a p-GaN gate were operated in the normally off mode at 350 °C. The temperature dependence of their performance was compared with the results of simulation.
