Abstract
Significant amount of pentacene can be dissolved in N-methylpyrrolidone (NMP) solvent. The solution color changed from deep purple to intense yellow. As the dissolution time increased, UV-visible absorption increased and several new absorption peaks were appeared. The solution was mixed with poly(3,4-ethylenedioxythiophene)poly(styrenesulfonate) (PEDOT:PSS). PEDOT:PSS or PEDOT:PSS doped with pentacene was spin-coated to the Al coated substrate. Au-electrode was fabricated on top of the semiconductor. Three-layered Schottkys diode comprised of Al, PEDOT:PSS or PEDOT:PSS-pentacene, and Au with thickness of 150nm, 420nm, and 1200nm, respectively were fabricated. The current densities of 4.8μA/cm2 at 2.5MV/m and 440μA/cm2 at 1.9MV/m were obtained for the Au/PEDOT:PSS/Al and Au/PEDOT:PSS-pentacene (3.2 mg)/Al Schottky diodes, respectively. The current density of Schottky diode enhanced about two order of magnitude by doping pentacene to PEDOT:PSS.
