Dynamic Transconductance Dispersion Characterization of Channel Hot-Carrier Stressed 0.25-
AlGaN/GaN HEMTs
Using the dynamic transconductance frequency dispersion technique, we characterize unstressed and hot-electron stressed short-channel AlGaN/GaN high-electron-mobility transistors. The results reported in this letter demonstrate that the stress-induced degradation in dc and pulsed characteristics is unlikely to be ascribable to sizable trap generation at the AlGaN/GaN interface.
