Effect of trapping on the critical voltage for degradation in gan high electron mobility transistors

We have performed V[subscript DS] = 0 V and OFF-state step-stress experiments on GaN-on-Si and GaN-on-SiC high electron mobility transistors under UV illumination and in the dark. We have found that for both stress conditions, UV illumination decreases the critical voltage for the onset of degradati...
