原始语种摘要: Abstract(#br)Thin films of pentacene (C 22 H 14 ) have become widely used in the field of organic electronics. Here films of C 22 H 14 of thickness ranging from submonolayer to multilayer were thermally deposited on Ag(111) surface. The determination of molecular geometry in pentacene films on Ag(111) studied by X-ray absorption at different stages of growth up to one monolayer is presented.(#br)XAS spectra at the C K-edge were collected as a function of the direction of the electric field at the surface. The different features of the spectra were assigned to resonances related to the various molecular unoccupied states by the comparison with the absorption coefficient of the pentacene gas phase. The transitions...
