Abstract
We have investigated the adsorption of ferrocene on graphite at low. temperatures (T- 140 K ) with high resolutio electro energy loss spectroscopy ( HREELS ). The vibrational modes indicate that the molecule is physisorbed with the ferrocene five-fold symmetric molecular axis oriented approximately perpendicular to the surface. Dosing onto the surface at elevated temperatures ( T> 280 K leads to thermal decomposition of ferrocene, producing particles on the graphite surface which have been studied with scanning tunnelling microscopy (STM ) at room temperature The particles are believed to consist predominantly of iron atoms arranged to form small metallic clusters.
