Mechanism for Conducting Filament Growth in Self‐Assembled Polymer Thin Films for Redox‐Based Atomic Switches

The switching mechanisms of atomic switches based on poly(ethylene oxide) (PEO) are systematically investigated. By using self-assembled PEO and Ag–PEO thin films, stack-structured devices exhibit stable bipolar switching behavior over 103 cycles. Direct observation of filament growth behavior in planar-structured devices reveals the effects of the polymer thin-film morphology, and the presence of electrochemically active electrodes, on the switching characteristics.
