Three terminal solid-electrolyte nanometer switch

We propose a three-terminal solid-electrolyte nanometer switch, where the control gate is separated from the current path. This novel switch resolves the issues arising from large current during switching (>1mA) in a two-terminal solid-electrolyte switch. We demonstrate that the drain current reversibly switches when a metallic bridge electrochemically forms or dissolves between the source and drain by applying gate voltage. The ON resistance is 200-300Omega and the ON/OFF current ratio is as high as 10
