N2 - Photoemission spectra and images of titanyl phthalocyanine films formed on graphite surfaces have been measured with 0.3 μm lateral and 30 meV energy resolutions. Islands of bilayer films were found to be formed in areas of monolayer films. Photoemission spectra revealed similarity/difference of molecular configurations between the bilayer islands and the well-annealed uniform bilayer films. The islands decayed slowly by migration of molecules. The results demonstrate the capability of photoemission microspectroscopy to resolve complicated electronic structures of realistic organic films.
