摘要
The authors have fabricated a 1.3 mu m-long gate AlGaN/GaN HEMT with f(T) of 14.1GHz, corresponding to a high f(T) x gate-length product of 18.3GHz mu m. By analysing the relationship between the delay time and the inverse of the drain current, the effective electron velocity in the channel was evaluated to be as high as 1.2 x 10(7) cm/s.
