Abstract :
The GaAs-based MOS-HEMT with oxide as the gate dielectric and HBTs with surface passivation prepared by liquid phase oxidation has been successfully demonstrated. As compared to its counterpart HEMTs, the larger gate swing voltages, lower gate leakage currents, and higher breakdown voltages make the proposed technique suitable for power device applications. Moreover, the HBTs with oxide passivation possess the characteristics of lower surface recombination currents, higher breakdown voltage, and improved higher dc current gain
