We present technology computer aided design (TCAD) results for wide band-gap Sn-doped α-GaO metal-semiconductor field-effect transistors (MESFETs). In particular, the effect of gate work function and electrode gap length on the electrical characteristics is demonstrated for a thorough understanding of the behavior of such devices. The gate work function significantly affects the reverse bias drain current under the gate-current dominant regime, whereas a gate-source/drain gap larger than 0.1 µm has a negligible effect on the drain current.
我们展示了宽带隙掺锡α-GaO金属半导体场效应晶体管（MESFET）的技术计算机辅助设计（TCAD）结果。特别是，展示了栅极功函数和电极间隙长度对电学特性的影响，以便全面了解此类器件的行为。在栅极电流主导区域，栅极功函数对反向偏置漏极电流有显著影响，而大于0.1 µm的栅源/漏极间隙对漏极电流的影响可忽略不计。
