InP-based high-electron-mobility transistors (HEMTs) with InAs quantum well exhibit record high-speed performances because of their high electron mobility and saturation velocity. In this work, we report on an InP-based HEMT with an InAs/In_0.8Ga_0.2As quantum well in the channel and a single Si δ-doping, which provide a high-speed operation for short-gate-length (L_G) HEMTs.
