Abstract:
We have investigated the structural and electronic properties of a pentacene film (similar to 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.
