摘要
Multi-level resistive switching characteristics of a Cu2O/Al2O3 bilayer device are presented. An oxidation state gradient in copper oxide induced by the fabrication process was found to play a dominant role in defining the multiple resistance states. The highly conductive grain boundaries of the copper oxide-an unusual property for an oxide semiconductor-are discussed for the first time regarding their role in the resistive switching mechanism.
