Angle-Resolved Photoemission from Oriented Films of Lead Phthalocyanine on a Cu(100) Surface

摘要

The orientation of large planar lead-phthalocyanine (Pb-PC) molecules relative to a Cu(100) single crystals substrate was determined for thin films in a photoemission experiment with use of synchrotron radiation to be parallel to the surface. For the uppermost valence band peaks with energies 5.8 and 8.3 eV below the vacuum level a psub(Z)-like emission pattern was observed in agreement with their ligand pi and Pb-6p origin.
