    A p-channel AlGaAs/GaAs heterostructure FET which operates in MIS-transistor like mode has been investigated for implementation in a complementary logic circuit. Maximum values of transconductances of 100 mS/mm at 77 K and 50 mS/mm at 300 K have been achieved in a device with 1 microm gate length. The improvement at 77 K is attributed to an increased mobility of the two-dimensional hole gas which was confirmed by Shubnikov-de Haas oscillations at 4.2 K.
