摘要

Anisotropic charge transport properties in organic semiconducting thin films of Boron Sub Phthalocyanine Chloride (Sub-Pc) have been studied by admittance spectroscopy applying a bias voltage parallel and perpendicular to the substrate. Sub-Pc long ordered structures confined in different directions induce anisotropic carrier mobility in films. The film with a thickness of 11nm exhibited carrier mobilities three orders higher along the substrate than perpendicular to it. Furthermore, AFM, Kelvin Probe, and UV-Vis spectroscopic studies corroborated the established mobilitystructure relationship. Published by AIP Publishing.
