Abstract

High quality WO₃/CoWO₄ core-shell nanowires have been successfully prepared by a hydrothermal process. Bipolar resistive switching behavior in a Ag/[WO₃/CoWO₄]/Ag device is demonstrated. The device can maintain superior stability over 100 cycles with an OFF/ON-state resistance ratio of about 333 at room temperature. The physical model of conducting filament formation due to the diffusion of Ag ions along the WO₃/CoWO₄ core-shell nanowires at high electric field has been suggested to explain the bipolar resistive switching behavior.
