Optically Controlled Memristor Using Hybrid ZnO Nanorod/Polymer Material

Jaafar, Ayoub H.; Kemp, Neil T.

Abstract

Controlling of resistive switching properties by optical means opens the route to new optoelectronics that can be written optically and read electronically. In this work, we demonstrate optically controlled memristors realized with a hybrid material of vertically aligned zinc oxide nanorods (ZnO NRs) and poly(methyl methacrylate) (PMMA). In addition to electronic switching, the devices are switchable by optical means upon illumination with UV light. The hybrid memristors require no forming step and exhibit multilevel switching behavior achieved by controlling either the DC sweep voltage or the UV light power. The optical memristor exhibits irreversible switching for the Off state, which has an important application in the fabrication of cloned neural networks with pre-trained information. The work provides a promising pathway for the fabrication of simple-to-make and low-cost optoelectronic devices for memory and optically tuned neuromorphic computing applications.
