Abstract(in English) | We have succeeded in suppressing short-channel effects by using high-Al-composition and extremely thin AlGaN barrier layers to improve high-frequency characteristics of sub-0.1-μm AlGaN/GaN heterostructure field-effect transistors (HFETs). The devices had maximum drain current densities of 1.1-1.2A/mm and peak extrinsic transconductances of 305-441mS/mm. The current-gain cutoff frequency (f_T) of 163GHz and maximum oscillation frequency (f_ |
