摘要

This paper describes comparative study of current collapse in AlGaN/GaN high-electron-mobility transistors (HEMTs) passivated with sputter-deposited SiO2 and SiNx dielectrics. The pulsed I-V measurements are employed to characterize switching response of the devices. It is found that the degree of current collapse for the SiNx-passivated device is superior to that for the SiO2-passivated device.
