P-channel A1GaAs/GaAs heterostructure FETs O-HFETs) employing two-dimensional hole gas (2DHG) were fabricated and their characteristics were measured at 300 and 77 K. The achieved extrinsic transconductances were respectively 16 mS-mm-1and 46 mSmm-1with a gate length of 1 μm. Calculations indicate that transconductances of more than 100 mSmm-1at 300 K and more than 200 mSmm-1at 77 K should be achievable in p-HFET devices. The above results demonstrate the possibility of employing/?-HFETs for complementary logic, workable even at room temperature.
