摘要

通过一步旋涂法制备了 Cu2AgBiI6 薄膜，并构建了 Ag/PMMA/Cu2AgBiI6/ITO 结构的柔性忆阻器。该器件表现出低开关电压的双极电阻开关行为，有利于降低能耗。此外，该研究还发现，该器件具有约 900 次循环的耐久性、超过 103 的较高导通/关断比、较长的保持时间（∼104 秒）以及较高的抗机械应力稳定性。值得注意的是，这种柔性忆阻器显示出了非凡的柔韧性和稳定性，即使在不同的弯曲角度或经历 900 次弯曲循环后，其电阻开关行为也没有发生显著变化。这项研究证明，无铅卤化物包晶 Cu2AgBiI6 可用于柔性电子器件的电阻随机存取存储器。

Flexible memristors with low-operation voltage and high bending stability based on Cu2AgBiI6 perovskite

Cu2AgBiI6 films were prepared by a one-step spin coating method, and flexible memristors with an Ag/PMMA/Cu2AgBiI6/ITO structure were constructed. The devices showed a bipolar resistive switching behavior with low switching voltage, which is beneficial for reducing energy consumption. Furthermore, this study found that the device exhibits an endurance of about 900 cycles, a higher ON/OFF ratio of over 103, a long retention time (∼104 s), and high stabilities against mechanical stress. Remarkably, the present flexible memristor displayed extraordinary flexibility and stability, with no significant change for the resistive switching behavior even at various bending angles or after undergoing 900 bending cycles. This study establishes that the lead-free halide perovskite Cu2AgBiI6 can be used for the resistive random-access memory of flexible electronics.
