Coexistence of bipolar and unipolar resistive switching behaviors in the double-layer Ag/ZnS-Ag/CuAlO2/Pt memory device
文摘

The coexistence of bipolar and unipolar resistive-switching (BRS and URS).

Increasing compliance current can realize the transformation from BRS to URS.

The CFs are composed of Ag atoms and Cu vacancies for BRS and URS, respectively.

The ZnS-Ag layer plays an important role in the RS localization.

The RS is located in the CuAlO2 layer, realizing the uniform BRS and URS.
