Abstract
SEXAFS and XARS on the Pt, L2, 3 edges for submonolayer and monolayer coverages on Si (111) 7 x 7 allow to recognize the growth mode of the Pt/Si silicide like interface, at room temperature. Chemisorption into sixfold interstitial sites in the top Si (111) double layer is followed by intermixing, and likely nucleation of Pt2Si coordinated clusters.
