Figure 5. Performance of the memory device.

Figure 5

(A) Typical I-V curve of a rGO/g-C3N4-NS/rGO device with arrows showing the voltage sweep direction. (B) The ON/OFF ratios of flexible memory diodes reported previously with nonmetal electrodes and insulator layer (Metal-free), metal electrode and nonmetal insulator layer (Metal electrode), metal-containing electrodes and insulator layer (Metal-based) compared with that of rGO/g-C3N4-NSs/rGO in current work. Inset: the pie chart of the percentage for each kind of flexible and rewritable memory diodes. This figure is derived from Table S1 in Supporting Information.
