Abstract

Vertically-stacked electronic devices having conductive carbon films are disclosed. The vertically-stacked devices exhibit non-linear current-versus-voltage response over a voltage sweep range in various embodiments. The vertically-stacked devices may be assembled into arrays where the vertically-stacked devices may be electrically addressed independently of one another. Uses of the vertically-stacked electronic devices and arrays as two-terminal memory devices, logic units, and sensors are disclosed. Crossbar arrays of vertically-stacked electronic devices having conductive carbon films and nanowire electrodes are disclosed.
