Abstract

Various embodiments of the present invention are directed to nanoscale electronic devices that provide nonvolatile memristive switching. In one aspect, a two-terminal device () comprises a first electrode (), a second electrode (), and an active region () disposed between the first electrode and the second electrode. The active region includes a mobile dopant (), and a fast drift ionic species (). The fast drift ionic species drifts into a diode-like electrode/active region interface temporarily increasing conductance across the interface when a write voltage is applied to the two-terminal device to switch the device conductance.
