We investigate the device characteristics of InAs-inserted-channel In/sub 0.52/Al/sub 0.48/As/In/sub 0.53/Ga/sub 0.47/As inverted high electron mobility transistors (HEMTs) with superconducting Nb electrodes. In these transistors, the ohmic contact between Nb and the two-dimensional electron gas formed in the InAs layer is obtained by contact with the Nb… CONTINUE READING
