<Title>Electronic states of CuPc chains on the Au(110) surface</Title> <Authors>Evangelista, Ferdinand; Ruocco, Alessandro; Gotter, Roberto; Cossaro, A.; Floreano, L.; Morgante, A.; Crispoldi, F.; Betti, M. G.; Mariani, C.</Authors> <Issue Date>2009-11</Issue Date> <Is part of>Jurnal of chemical physics</Is part of> <Volume>131</Volume> <Pages>174710</Pages> <Abstract>The electronic properties of Cu-phthalocyanine (CuPc) molecules flatlying along the channels of the Au(110) reconstructed surface have beeninvestigated by means of ultraviolet and x-ray photoelectronspectroscopy. The ordered chains give rise to a highly orderedsingle-layer structure with a (5x3) symmetry. Although from thecore-level analysis not any significant charge transfer between themolecules and the underlying Au surface is observed, the valence bandphotoemission data bring to light CuPc-induced features localized atthe interface. In particular, energy versus momentum dispersion of aninterface state reveals a bandwidth of about 90 meV along the enlargedAu channels, where the CuPc chains are formed, with a defined fivefoldsymmetry well fitting the CuPc intermolecular distance.</Abstract>
