The electronic state of the organic/inorganic interface has not been unveiled well. In this study, the electronic state of pentacene/graphite was measured by low-energy angular resolved photoelectron spectroscopy. The dispersive band which is absent in the pristine substrate spectra appears and showed a constant final state feature. These features indicate that it could be originated from a newly-formed conduction band at the weakly bounded interface visualized by high-resolution angle-resolved secondary electron emission.
