Comparison of angular resolved photoemission on Pt(110) with DFT bulk band calculations — •Alexander Menzel, Christian Braun, Peter Amann, and Erminald Bertel — Institute forPhysical Chemistry, University of Innsbruck, Austria

Angular resolved photoemission (ARPES) experiments of clean and halogenated Pt(110) are compared with the DFT-derived bulk band structure of Platinum. Numerous dispersion features agree with the calculated one-dimensional density of states (kz-histogram) indicating emission from near surface transitions. In order to distinguish the effects of initial state (surface resonances), matrix element (surface photoemission) and final state (strong photoelectron damping), we varied incident polarization, photon energy, and surface phase symmetry.
