An In/sub 0.52/Al/sub 0.48/As/n/sup +/-In/sub 0.53/Ga/sub 0.47/As MISFET with a modulation-doped channel


A heterostructure metal-insulator-semiconductor field-effect transistor (MISFET) with a modulation-doped channel is proposed. In this device, a very thin undoped subchannel is located between the undoped wide-bandgap insulator and a thin heavily doped channel. In the depletion mode of operation, electron transport takes place along the heavily doped channel… (More)
