Development of printable atomic switch devices

采用喷墨打印的方法在塑料基板上制作了无间隙型原子开关。利用金属电极和衬底之间的表面能的高对比度，可以在电极上沉积薄的SPE膜。所制备的Ag/SPE/Pt电池在真空和大气中的电偏压下表现出双极阻变行为，这归因于电极之间金属丝的形成和溶解。电池也表现出稳定的开关行为下弯曲的基板。结果表明，SPE印刷原子开关在柔性开关/存储器应用中具有很大的潜力。

Gapless-type atomic switches were fabricated on a plastic substrate using an inkjet printing of a solid polymer electrolyte (SPE). Using a high contrast in the surface energy between a metal electrode and the substrate, a thin SPE film could be deposited just over the electrode. The fabricated Ag/SPE/Pt cells showed bipolar resistive switching behavior under electrical bias in vacuum and atmosphere, which is attributed to the formation and dissolution of a metal filament between the electrodes. The cells also exhibited stable switching behavior under bending of the substrate. The obtained results demonstrate that the SPE-printed atomic switch has great potential for flexible switch/memory applications.
