Novel Organic Schottky Barrier Diode Created in a Single Planar Polymer Film.

An organic Schottky barrier diode is created in a single planar PEDOT:Tos film by treating a half of the PEDOT:Tos film with TDAE vapor. Current is rectified in one direction by the Schottky barrier at the junction. The unique planar structure made of a single film greatly reduces defects, resulting in a remarkably high current density with a high rectification ratio, as well as making it suitable for ink-jet-type or roll-to-roll printing techniques.
