摘要
Current collapse in ALGaN/GaN HEMTs has been investigated using photo-ionisation spectroscopy techniques to probe the spatial origins of the traps producing this effect. The results indicate that the responsible traps reside in the high-resistivity GaN buffer layer and are identical to those traps causing current collapse in GaN MESFETs.
