abstract = "The surface of directly coated TiO2 nanoparticles on the Al-electrode has many nanoscale holes and cracks. The defects of the TiO 2 layers can be removed via coating PEDOT:PSS on top of the TiO 2 layer. Schottky diodes having various thicknesses of the TiO 2 layers and PEDOT:PSS layers were fabricated. The normalized forward current densities were almost the same for the Schottky diodes fabricated with various thicknesses of the TiO2 layers. The current densities of the Schottky diodes with double coatings have large deviation. The log(J) vs. log(V) and shows nonlinear J-V characteristics representing the multiple electron emission mechanisms such as space-charge limited conduction, Poole-Frenkel emission, or thermoionic emission. The plots of log(J) vs. E1/2 and log(J/E) vs. E1/2 show nonlinear behavior and with two distinctive slopes. Based on these results, the electron emission mechanism may have two distinctive mechanisms including Schottky emission mechanism and Poole-Frenkel emission mechanism.",
