In this paper, this resistive switch mechanism of the Au/ZnO/Au crossbar structure was investigated. Au has been considered as a good metallic electrode for its low oxygen affinity and high stability. Au/ZnO/Au crossbar was deposited using sputtering. The crossbar area size is 100 um2 with ZnO layer thickness ∼140 nm and Au electrodes layer ∼60 nm. The bipolar resistive switching behavior can be observed in our device, which the set voltage (VSET) and the reset voltage (VRESET) is -2.25V. By further electrical transport analysis, the space-charge-limited-current (SCLC) dominate the carrier transport in the high resistance state (HRS). On the other, low resistance (LRS) is follow the ohmic transport. Our result
shows that the oxygen ion migration plays an important role in the resistive switch mechanism.
