摘要
介绍了AlGaN/GaNHEMT器件的研制及室温下器件特性的测试 .漏源欧姆接触采用Ti/Al/Pt/Au ,肖特基结金属为Pt/Au .器件栅长为 1μm ,获得的最大跨导为 12 0mS/mm ,最大的漏源饱和电流密度为 0 95A/mm .
The fabrication of AlGaN/GaN HEMT and its properties at room temperature is reported.Source drain Ohmic contacts and Schottky metal system is Ti/Al/Pt/Au and Pt/Au,respectively.A maximum transconductance of 120mS/mm and a saturated current density of 0 95A/mm are obtained.
