Abstract :
The self-rectifying resistive switching behavior is investigated in the Au/ZrO2: nc-Au/n+ Si sandwich structure with the Au nanocrystals embedded ZrO2 films (ZrO2: nc-Au) fabricated by e-beam evaporation. The rectification ratio is obtained to be 7×102 under ±0.5 V at low-resistance state (LRS), which can alleviate the cross talk effect in crossbar structure arrays without additional switching elements. The different current conduction mechanisms at LRS are studied. A model is proposed to explain this self-rectifying resistive switching behavior.
