Abstract
An electronic bistable device with a composite structure was fabricated using tapered ZnO nanorod arrays (ZnO NRs) coated with carbon quantum-dots (C QDs). With the addition of C QDs, the ON/OFF resistance ratio is 6Ã102, over 100 times higher than that of device with pristine ZnO NRs. The effect of C QDs on the resistive switching behavior was investigated by current-voltage (I-V) and capacitance-voltage (C-V) characterization. The conduction mechanisms of the devices were discussed using space charge limited current (SCLC) model.
