Title: | Self organization of pentacene grown on Cu(1 1 9) | Authors: | Annese, E. Viol, C.E. Zhou, B. Fujii, J. Vobornik, I. Baldacchini, C. Betti, M.G. Rossi, G. |
Journal: | SURFACE SCIENCE | Issue Date: | 2007 | Abstract: | We have investigated the structural and electronic properties of a pentacene film (∼2 nm) grown on the Cu(1 1 9) substrate using scanning tunneling microscopy (STM) and synchrotron based angle-resolved UV photoelectron spectroscopy at room temperature. STM images indicate an ordered superstructure of pentacene molecules lying almost flat with respect to the substrate. From angular-resolved photoemission spectra, we have observed an energy-band dispersion of about 100 meV for the highest occupied molecular orbital in the direction perpendicular to the pentacene surface. © 2007 Elsevier B.V.
