    Abstract:

    The superconductivity induced by the proximity effect in a two-dimensional electron gas (2DEG) in the inversion layer on p-type InAs was confirmed using a Nb-InAs-Nb junction. It was also shown with a metal-insulator-semiconductor gatefitted junction that the supercurrent in the 2DEG could be controlled by the gate voltage (electric field effect). The controllability of the supercurrent is discussed considering the change in the coherence length of the 2DEG.
