Abstract
PURPOSE:To obtain a stable three-terminal superconducting element admitting of more freedom in element design by a method wherein a heterojunction structure is incorporated into a semiconductor layer by modulated doping. CONSTITUTION:When a gate voltage not lower than a heterojunction threshold value Vth is applied, electrons out of a doped AlxGa1-xAs layer 4 are accumulated in the surface of an undoped GaAs layer 2 that is a channel layer, which generates a two-dimensional electron distribution. With the GaAs layer 2 and an AlxGa1-xAs layer 3 on the carrier-supplying side being undoped, there will be a very high carrier mobility. In consequence, a large coherence length xsiis available, a superconductive connection is established across a source and drain electrodes 6 and 7, which allows a large superconduction current to allow.
