Improved Gate Reliability of p-GaN Gate HEMTs by Gate Doping Engineering
Guangnan Zhou, Fanming Zeng, Rongyu Gao +4
We present a novel p-GaN gate HEMT structure with reduced hole concentration near the Schottky interface by doping engineering in MOCVD, which aims at lowering the electric field a…

Determination of the Gate Breakdown Mechanisms in p-GaN Gate HEMTs by Multiple-gate-sweep Measurements
Guangnan Zhou, Fanming Zeng, Yang Jiang +5
In this work, we studied the gate breakdown mechanisms of p-GaN gate AlGaN/GaN HEMTs by a novel multiple-gate-sweep-based method. For the first time, three different breakdown mech…

Oxygen-based digital etching of AlGaN/GaN structures with AlN as etch-stop layers
Jingyi Wu, Siqi Lei, Wei-Chih Cheng +5
O2-plamsa-based digital etching of Al0.25Ga0.75N with a 0.8 nm AlN spacer on GaN was investigated. At 40 W RF bias power and 40 sccm oxygen flow, the etch depth of Al0.25Ga0.75N wa…
