Abstract
Based on SEXAFS results for 0.5, 1 and 2 ML (monolayers) of Co deposited onto Si(111) 7 × 7 at room temperature, we obtain the structure of the chemisorption in this model system. The 7 × 7 order of the substrate determines the chemisorption geometry and coordination numbers for the first 0.7 ML of Co. At 2 ML a Co-rich overlayer covers the interface.Keywords
