Abstract
Molybdenum trioxide (MoO3) doped organic semiconductors have shown attractive applications in organic electric devices. The authors carried out an investigation on the origin of enhanced photoelectric characteristics in MoO3-doped pentacene films. Electrical properties including charge transport, trap density and conductivity in bulk MoO3-doped pentacene films were investigated through fundamental measurements of current-voltage characteristics. Electrical structure and conducting mechanism in MoO 3-doped pentacene films were further evaluated by X-ray diffraction and X-ray photoelectron spectroscopy measurements. The experimental results suggest that the improved conductivity in MoO3-doped pentacene film was partly associated with the increased ratio of low Mo oxidation state (Mo4+) with a fact of better conducting property of MoO2 than that MoO3.
