| Research Abstract |
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.
