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.
