Abstract
AlSb/InAs HEMTs have been fabricated using Si-doping in a very thin (9 A) InAs layer located in the upper AlSb barrier. Quantum Hall measurements show that there is no parallel channel. Devices with a 0.5 μm gate length exhibit a drain current density of >1 A/mm and an f TLg product of 30 GHz μm at V(DS)=0.4 V after correction for the gate bonding pad capacitance
