Determination of graphitic carbon structure adsorbed on Ni(110) by surface extended energy-loss fine-structure analysis

Abstract

A model is proposed for the geometrical structure of graphitic carbon chemisorbed on a Ni(110) single crystal which reproduces with good accuracy the experimental radial distribution function $F(R)$ obtained for the first time by surface extended energy-loss fine-structure spectroscopy. The graphitic layer strongly interacts with the Ni substrate. We find that some carbon atoms are placed in the fivefold symmetry site of Ni.
