Low leakage and high blocking voltage GaN-on-GaN Schottky diode by TMAH surface treatment

Low leakage and high blocking voltage GaN-on-GaN Schottky diode by TMAH surface treatment

In this study, the impact of surface treatment by TMAH and HF on the electrical characteristics of GaN-on-GaN Schottky diodes is examined through I–V and C–V characterizations. A TMAH surface treatment leads to an improvement in the reverse characteristics of the devices and improvement in breakdown...
