Abstract

MBE-deposited Sc₂O₃ films are found to effectively passivate surface states in the gate-drain region of AlGaN/GaN HEMTs. The effect of the passivation is observed in higher forward I_DS-V_DS three-terminal breakdown voltage and output power under class A operation. In the latter case, the power-added efficiency was at least doubled.
