A three-terminal superconducting device composed of a semiconductor-coupled Josephson junction and an oxide-insulated gate was tested at 4.2K. It was possible to control the coherence length ξn in the semiconductorby applying a gate voltage; consequently, the junction's critical current, whichdepends on ξn', was changeable. Power dissipation and switching time constant would be expected to be approximately 1 μW and 10 ps, respectively.
