摘要

This letter reports a simple processing method for fabricating metal-oxide-semiconductor high-electron-mobility transistors (MOS-HEMTs) by using hydrogen peroxide (H ₂O ₂) oxidation technique. Aluminum oxide (AlO _x) was formed on the surface of the AlGaN barrier as the gate dielectric of the MOS-gate structure. By using the capacitance-voltage measurement, the dielectric constant (κ) of AlO _x was determined to be 9.2. The present MOS-HEMT has demonstrated enhanced saturation drain current density at V _GS = 0 _V (I _DSS0) of 552.3 mA/mm, maximum extrinsic transconductance (g _max) of 136 mS/mm, wide gate voltage swing of 2.9 V, and two-terminal gate-drain breakdown/turn-on voltages (BV _GD/V _on) of-132.2/1.82 V.
