Resistive switching behaviors of ZnO nanorod layers

This is the authors' abstract. We don't add key points for this paper.

We have fabricated vertically aligned ZnO nanorod layers (NRLs) on indium tin oxide (ITO) electrodes using a hydrothermal process. The Pt/ZnO NRL/ITO capacitor exhibits bipolar resistive switching behavior. The resistive switching behavior may be related to the oxygen vacancies and/or zinc interstitials confined on the surface of the ZnO NRs, giving rise to the formation of straight and extensible conducting filaments along each vertically aligned ZnO NR. Superior stability in resistive switching characteristics was also observed, demonstrating that ZnO NRLs have the potential for next-generation nonvolatile memory applications.
