摘要：
In this paper, a novel enhancement-mode AlGaN/GaN double-barrier gates-separating groove heterostructure field-effect transistor (DB-GSG HFET) is proposed, in which two block harriers exist among the three gates as realized by dry etching. Because of the shielding effect of drain-side block barrier on drain voltage, the source-side block barrier is almost unaffected by drain voltage in the DB-GSG HFET. As a result, the electrical characteristics of the DB-GSG HEFT are improved obviously, compared with the gates-separating groove (GSG) HFET which has only one single block harrier between double gates.
