Silver Nanofilament Formation Dynamics in a Polymer-Ionic Liquid Thin Film by Direct-Write.

Silver nanofilament formation dynamics are reported for an ionic liquid (IL)-filled solid polymer electrolyte prepared by a direct-write process using a conductive atomic force microscope (C-AFM). Filaments are electrochemically formed at hundreds of locations on a 40 nm thick polymer electrolyte, polyethylene glycol diacrylate (PEGDA)/[BMIM]PF. Although the formation time generally decreases with increasing bias from 0.
