Filamentary switching of Rose Bengal devices
(English)Manuscript (preprint) (Other academic)
Switch devices with a structure of metal / orgamc layer / metal were fabricated, with the organic layer being Rose Bengal sodium salt, Rose Bengal bis(tricthylammonium) salt, Rose Bengal lactone and Fluorescein. All devices showed reversible switch behavior, ruling out electro reduction or conformational switching. Furthermore, only devices with ITO as substrate and Al or Ag as top electrode showed reversible switch behavior. Electrical characterization of the ITO substrate indicated that the switching is due to the reversible formation of conducting filaments, initiated from the ITO.
