Figure 3From: Unipolar resistive switching of ZnO-single-wire memristorsI-V curves in a log-log scale and I-V curves of HRS under a high-electric field. (a) I-V characteristics of the Ag/ZnO/Ag device in log scale. (b) The plots of lnI-V1/2, ln(I/V)-V1/2, and I-V2 for the Schottky, PF, and SCLC conduction mechanisms, respectively.Back to article page
