An ionic bottle for high-speed, long-retention memristive devices

Abstract

We propose a new type of bipolar resistive switch or memristive device, based on an ionic bottle, which is characterized by both low switching energy and high state retention time. The ionic bottle is engineered such that image charges on metallic electrodes trap ions inside a semiconducting film when there is no applied bias voltage, but an external field can drive ions through one of the electrodes into an adjacent semiconducting film to accomplish a nonvolatile resistance change. © The Author(s) 2011.
