Volage-current (V-I) curves of the PEDOT:PSS/ZnO NRs/GZO heterojunctions exhibited a rectification behavior with hysteresis loops both in forward and reverse voltage regions. Under the irradiation of the ultraviolet (UV) light of 360 nm, the hysteresis loop area in the forward voltage region decreased, but that in the reverse voltage region increased. Both the ln V vs. ln I plots and Fowler-Nordheim (F-N) plots (i.e. ln (I/V2) vs. 1/V) for the voltage increase in the forward voltage region in a dark state can be clearly divided into three characteristic regions. The V-I curve showed an ohmic characteristic in the low voltage region, whereas the current was approximately proportional to the fourth power of the forward voltage in the high voltage region. Therefore, the possible transport mechanisms in the low and high voltage regions are direct tunneling and F-N tunneling, respectively. In the medium forward voltages, the current was approximately proportional to the square of the forward voltage, which is characteristic of space-charge-limited conduction. The increase in repetition number of V-I measurement under the forward voltage (0→3→0 V) in a dark state led to the increase in maximum forward current. |
