    Depletion- and enhancement-mode Al0.48In0.52As/Ga0.47In0.53As modulation doped field effect transistors with 1 μm gate length have been successfully fabricated by employing a recessed gate structure and an undoped Al0.48In0.52As top layer beneath the gate metal. The fabricated devices exhibited good DC characteristics with a high transconductance and a complete pinch-off characteristic. For both depletion- and enhancement-mode devices, the transconductances of 250 mS/mm and 300 mS/mm have been measured at 300K and 77K, respectively
