| Abstract: | Low-temperature scanning tunnelling microscopy of submonolayers of PTCDA adsorbed on 2H-NbSe2 reveals an adsorbate layer that is neither commensurate with the substrate lattice nor with the charge density wave periodicity. The observed smallness of deviations from the PTCDA bulk-state unit-cell dimensions indicates that PTCDA film formation is dominated by intermolecular interactions rather than by interaction between PTCDA and 2H-NbSe2.
