Abstract

Electro-thermal behaviour and degradation of recessed GaN Schottky diode are studied under forward and reverse ESD stress. Impact of different surface treatments at Schottky interface, on trap generation and degradation is investigated. Evolution of mechanical stress and defects is probed using onthe- fly Raman spectroscopy. Distinct failure modes are discovered in each case.
