New degradation mechanism observed for AlGaN/GaN HEMTs with sub 100nm scale unpassivated regions around the gate periphery
We study the sub 100nm scale unpassivated regions around the gate periphery. The void influences the DC- and optical characteristics of the AlGaN/GaN HEMTs. The void leads to the effects and mechanisms observed. It improves the understanding of device performance and degradation mechanisms.
