全体主题 > Device characterization and modeling

GaN-based enhancement-mode FinFET with double-channel AlGaN/GaN heterostructure is proposed. The DC characteristics of device is simulated by sentaurus TCAD software. The simulation results show that the double-channel AlGaN/GaN with doped barriers can improve the channel current. Furthermore, The combination of FinFET and double-channel structure can improve the saturation current and the control ability of the gate, the enhancement-mode device can be obtained with the 30nm Fin-width, and the peak transconductance reaches 417mS/mm.
