Abstract

The simple and cost-effective method to form vanadium oxides (VOx) with high density of gap-states and role of gap-states for organic electronics were investigated. The percentage of V2O5 decreased from 82.7% to 29.3% as the deposition rate increased from 0.1 to 1.0Å/s in thermal evaporation. Synchrotron radiation photo emission spectroscopy revealed that a number of gap states relating to oxygen vacancies was induced near the Fermi level, transporting charges and lowering the hole injection barrier from 0.92 to 0.67eV. As a result, the operation voltage at 1mA/cm2 was reduced from 8.3 to 5.2V
