Abstract
Polymer Schottky diodes using p-type poly(3,4-ethylenedioxythiophene:poly (styrenesulfonate) (PEDOT:PSS) doped with various concentrations of n-type TiO2 nanoparticles have been fabricated. Although Al/PEDOT:PSS/Au Schottky diode does not show a clear diode characteristics, the Al∕TiO2-PEDOT:PSS/Au Schottky diode exhibites excellent rectification characteristics. A Schottky diode with highly doped TiO2 nanoparticles (20wt%) shows high forward current having more than three orders of magnitude with respect to pristine PEDOT:PSS Schottky diode. The conduction mechanism of the TiO2 doped Schottky diodes shows best fit of space charge limited conduction process compared to the other mechanisms including Schottky emission and Poole–Frenkel emission.
