摘要：A Fe2O3 film homojunction was orderly prepared by magnetron sputtering and a hydrothermal method. The Fe2O3 homojunction-based memristor exhibits an obvious self-selective effect as well as a typical analogue resistive switching (RS) memory behavior. A desirable self-rectifying voltage range (-1 to 1 V), stable resistance ratio, good cycling endurance (> 10(4) cycles), and long retention time (> 10(4) s) can be obtained from the Fe2O3 homojunction-based memristor. Oxygen vacancies (V-o) are inevitably generated during the growth of the Fe2O3 film. The self-selective analogue RS memory behavior is ascribed to the electron tunneling behavior between the potential barrier generated by the FeOx contact and the electron filling dynamic in the V-o-based traps. This work provides a simple method to prepare a self-selective analogue memristor and lays the foundation for the core device of neuromorphic computing.
