Abstract

Organic bistable memory devices (OBDs) with size-controlled polypyrrole (PPy) nanoparticles are developed by employing conducting PPy nanoparticle-embedded poly(vinyl alcohol) (PVA) as an active layer in OBDs. Monodisperse polypyrrole (PPy) nanoparticles with different diameters (20, 60, and 100nm) are fabricated via dispersion polymerization in order to evaluate size-dependent bistable memory characteristics. Stable multilevel switching and a high on/off ratio over 100 were demonstrated with 20nm of PPy in the OBDs.
