Abstract

A microelectronic thin-film device having a thin superconducting layer in contact with a thin quasi-insulating conversion layer. The critical current of the superconducting layer is controlled by application of a voltage to the conversion layer by means of a gate electrode, causing the conversion layer to undergo an insulator-metal transition.
