Abstract
Abstract Molybdenum trioxide (MoO 3 ) 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 MoO 3 -doped pentacene films. Electrical properties including charge transport, trap density and conductivity in bulk MoO 3 -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 MoO 3 -doped pentacene film was partly associated with the increased ratio of low Mo oxidation state (Mo 4+ ) with a fact of better conducting property of MoO 2 than that MoO 3 .
