An all-solid-state electric-double-layer transistor was fabricated for electric modulation of the superconducting critical temperature. A shift of superconducting critical temperature was achieved by electrostatic carrier doping via electric-double-layer at superconductor/alkali metal ion conducting solid electrolyte interface. This solid electrolyte gating method should enable development of practical superconducting devices highly compatible with other electronic devices.
