摘要: We studied the structural and electronic properties of 2,3,9,10-tetrafluoropentacene (F4PEN) on Ag(111) via X-ray standing waves (XSW), low-energy electron diffraction (LEED) as well ultraviolet photoelectron spectroscopy (UPS XPS). XSW revealed that adsorption distances F4PEN in (sub)monolayers were 3.00 A for carbon atoms 3.05 fluorine atoms. The monolayer was essentially lying Ag(111), multilayers adopted π-stacking. Our study shed light not only F4PEN-Ag(111) interface but also fundamental behavior fluorinated pentacene derivatives metals context energetics growth mode.
