Abstract

This paper reports a polymer-based flexible Schottky diode made on a flexible cellulose substrate with poly(3, 4-ethylenedioxythiophene):poly(styrenesulfonate)-pentacene (PEDOT:PSS). Pentacene was dissolved into the N-methylpyrrolidone (NMP) solvent and mixed with PEDOT:PSS. Three-layered Schottky diodes consisting of Al, PEDOT:PSS or pentacene-PEDOT:PSS, and Au were fabricated. The current density of Au/PEDOT:PSS/Al Schottky diode (4.8 muA/cm² at 2.5 V/mum) was drastically improved to 440 muA/cm² at 1.9 V/mum when the pentacene-PEDOT:PSS was used. This enhancement of current density of Schottky diode is promising for flexible electronic devices.
