Abstract

See full text

Various embodiments of the present invention are directed to nanoscale electronic devices that provide nonvolatile memristive switching. In one aspect, a two-terminal device (600) comprises a first electrode (602), a second electrode (604), and an active region (606) disposed between the first electrode and the second electrode. The active region includes a mobile dopant (608), and a fast drift ionic species (610). 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.
