Transparent organic bistable memory device with pure organic active material and Al/indium tin oxide electrode

Abstract

Transparent organic bistable memory devices OBDs were developed by employing indium tin oxide ITO as an anode and a cathode for OBD. A cathode structure of aluminum Al /ITO was used and bistability could be realized with pure polyphenylenevilylene based polymer active material without any metal nanoparticle. Transmittance of over 50% could be obtained in Al/ITO based OBD at an Al thickness of 10 nm, and an average on/off ratio around 100 was observed.
