AlGaN/GaN HEMTs with different passivation layers were studied using pulsed I-V system. The maximum drain current showed higher values at pulsed conditions as compared with DC for SiN passivation, and vice versa for Al2O3, SiO2 and without passivation. The drain current decreased with increasing the on-state time for SiN, which indicated that the most probable location of trap was at the AlGaN layer beneath the gate. Increasing tendency of drain current with increasing on-state time indicated that the surface traps were dominant for this behavior, which was the case for Al2O3, SiO2, and without passivation. |
