“…At present, the major route to developing memristive materials is to improve material synthesis methods and broaden the material systems. [176][177][178][179][180] This is mainly reflected in optimizing the preparation and growth of materials. On the other hand, it is necessary to continuously improve the interface effect of materials and conduct more in-depth research on the special properties of materials in different dimensions.…”

“…In this study, CH 3 NH 3 PbI 3 micro/nanowires were synthesized by a rapid liquid−solid growth from supersaturated solution, as described in detail in our previous publication. 50 After synthesis, individual micro/nanowires were transferred onto a treated Kapton insulating substrate. To fabricate an asymmetric double-terminal device, semidry Ag and C pastes were fixed on two ends of a single micro/nanowire, respectively, and then copper wires were connected to the two electrodes.…”

“…This phenomenon was ascribed to the presence of AgI x formed at the interfaces of the two Ag/MAPbI 3 layers, consequently engendering a tunnel barrier. 47,48 Nevertheless, replicating this phenomenon within MAPbI 3 thin films posed a significant challenge. We attempted various approaches to modulate the tunneling barrier at the interface of perovskite thin film devices (as illustrated in Fig.…”
