Surface extended-x-ray-absorption fine-structure study at the carbon<i>K</i>edge: The p4g(22)-C/Ni(100) system

Abstract

The surface extended-x-ray-absorption fine structure (SEXAFS) has been studied at the carbon K edge for the p4g(2\ifmmode\times\else\texttimes\fi{}2)-C/Ni(100) adsorption system. The results are in good agreement with the fourfold hollow site proposed in a previous low-energy electron diffraction study. The successful measurement of carbon SEXAFS from adsorbed species opens up new possibilities in surface science.
