Abstract
Space-charge-limited conductivity in thin vacuum-evaporated cc-form copper phthalocyanine (CuPc) films with columnar molecular structure perpendicular to the substrate plane was investigated. The shape of current-voltage char acteristics and the density-of-states function (DOS) were strongly influenc ed by adsorbed oxygen. Oxygen formed hole traps distributed in energy about 0.38 eV deep.
