Abstract

The unusual adsorption geometry of the large graphene-like polycyclic aromatic hydrocarbon hexa-peri-hexabenzocoronene (HBC) across kinks on the stepped vicinal Au(111212) surface has been studied by synchrotron radiation X-ray photoelectron diffraction (XPD) and scanning tunneling microscopy (STM). By a combination of the two techniques a complete characterisation of the adsorption behaviour is achieved, yielding information on preferential adsorption sites (STM) and molecular orientation (XPD). At low coverage (
