摘要

Fabrication of single crystal hydrogen-terminated diamond MOSFET with YSZ/Al₂O₃ bilayer dielectrics has been successfully carried out. The flat band voltage shift and hysteresis voltage were small in the capacitance-voltage curve. The dielectric constant of YSZ/Al₂O₃ was calculated, and the fixed and trapped charge densities in dielectrics were deduced based on the capacitance-voltage curve. According to the transfer characteristics curve, on/off ratio and breakdown voltage were extracted. Distinct pinch-off and p-type channel were shown in the output characteristics curve. The effective mobility was evaluated to be 80.4 cm² V⁻¹ s⁻¹ at V_GS = −1.5 V based on the relation between on-state resistance and 1/|V_GS-V_TH|.
