Role of oxadiazole moiety in different D–A polyazothines and related resistive switching properties

“…5,31,32 In particular, electronic memories based on D-A polymers with a large on/off ratio, good endurance, long retention time, low power consumption and fast switching speed have been investigated extensively over the past few years. [33][34][35][36] Nevertheless, there are still challenges in D-A polymer memories, where the lack of a comprehensive and clear understanding of the electronic origin that causes the resistance transition hinders the development of high-performance materials for practical memory applications. [37][38][39] Poly(Schiff base) materials are a family of conjugated polymers containing imine groups (C]N) in the backbone and exhibiting excellent thermal stability, good mechanical properties, metal-chelating ability and molecular doping-controlled electrical properties.…”

Controlling Reversible Dielectric Breakdown in Metal/Polymer Nanocomposites

“…Overall, our experiments demonstrate that AuNR/polymer arrays are a versatile class of nanostructured materials allowing for the manipulation of both the threshold voltages of REB and the hysteretic behavior accompanying material relaxation. The ability of the nanorod/polymer composites to transition reversibly between the low‐ and high‐conductance states suggests possible applications of these materials as switches or sensors (e.g., photosensors based on azobenzene isomerization) and also as elements of non‐volatile memory devices (although an obvious drawback here is that the switching times are much longer than in traditional electrically bistable materials based on electronic29–31 or redox effects32). From a fundamental point of view, we believe that this system, and others similar to it, can provide a convenient test bed for studying the reorganization dynamics of polymers under electrical bias–perhaps the most intriguing question here is the structure of the conductive filaments that form when the polymers break down.…”
