A general phenomenological model is presented for obtaining the zero Kelvin work function of any crystal facet of metals and semiconductors, both clean and covered with a monolayer of electropositive atoms. It utilizes the known physical structure of the crystal and the Fermi energy of the two-dimensional electron gas assumed to form on the surface. A key parameter is the number of electrons donated...
The orientations of halobenzenes (C 6 H 5 Cl and C 6 H 5 I) and phenyl (C 6 H 5 ) groups adsorbed on a Cu(111) surface have been studied by the near edge X-ray absorption fine structure (NEXAFS) method. For near-monolayer coverages, both chlorobenzene (C 6 H 5 Cl) and iodobenzene (C 6 H 5 I) bond with the plane of their...
