Abstract

Superconductor-two-dimensional electron gas-superconductor (S-2DEG-S) junctions derive much of their recent interest from potential applications in a three-terminal transistor based on the Josephson effect. The ability of an electric field to penetrate into a 2DEG would allow one to modulate the critical supercurrent of the Josephson junction by means of the voltage on a gate electrode, in much the same way as one can modulate the conductance of a field-effect transistor in the normal state. Of particular interest are junctions which show a quantum-size effect on the conductance, since one would then expect a relatively large field-effect on the critical current [1]. Quantum-size effects on the conductance have been studied extensively in nanostructures such as quantum point contacts and quantum dots. The corresponding effects on the Josephson current have received less attention.
