Abstract

A hyper-branched polymer (HPS) with dithiocarbamate (DC) end groups and gold nanoparticle stabilized by HPS (HPSAu) were synthesized. We fabricated a single-layered organic electrical bistable device (OBD). It exhibited a unipolar switching behavior with a negative differential resistance (NDR). When a certain voltage was applied to the pristine state, the device changed irreversibly and began exhibiting bistable conductive states; the equivalent circuit of this device is a parallel circuit comprising one resistance and one capacitor.
