  • Abstract
    The authors report the first successful growth and fabrication of high-performance, planar-doped pseudomorphic GaInAs/AlInAs HEMTs. Hall mobilities as high as 11900 cm2/Vs (300 K) with sheet-electron concentrations of 2.4×1012 cm-2 were measured for the heterostructures. A drain-saturation current of 1 A/mm, a transconductance of 420 mS/mm, and an extrapolated ft of 64 GHz were achieved in a 0.5 μm gate-length HEMT
