Characteristics of multilevel bipolar resistive switching in Au/ZnO/ITO devices on glass

초록

In this study, we characterize multilevel bipolar switching in devices composed of Au/ZnO/ITO constructed on glass. The ratio of the measured resistance in the low-resistance state (LRS) to that in the high-resistance state (HRS) depends on the starting sweep voltage. The HRS/LRS ratio increases from 10 to 10(4) as the starting sweep voltage changes from -1 to -3.5 V. Moreover, the Au/ZnO/ITO devices can complete more than 10(2) cycles and maintain their characteristics for up to 10 years. A more detailed description on the multilevel bipolar switching of our devices will be given in this paper. (C) 2011 Elsevier B.V. All rights reserved.
