Abstract
AlGaAs/GaAs high-performance, minority-carrier, induced-channel, heterojunction field-effect transistors (HFETs) fabricated on semi-insulating GaAs using molecular beam epitaxy (MBE) are reported. A 0.6 mu m self-aligned gate HFET exhibited a room-temperature transconductance of 540 mS/mm with a cutoff frequency of 25 GHz.
