Outline of Final Research Achievements

While organic electronic devices have undergone rapid paced progress, fundamental mechanisms of charge carrier transport is still under debate mainly because of insufficient knowledge on the electronic structures of organic semiconductor materials. This study has targeted at complete demonstration of the electronic states which contribute to the charge carrier transport in the organic semiconductor materials through development of original photoemission measurement techniques of high-precision and high-sensitivity. As a representative achievement, valence band dispersion of the single crystal pentacene, a proto-typical p-type organic semiconductor molecule, were experimentally figured out for the first time. Inter-molecular transfer integral and the effective mass of conductive holes were derived from the present results, which suggests an intermediate character of the charge carrier transport between inter-molecular hopping of localized particles and continuous propagation of waves.
