We have investigated the adsorption of ferrocene on graphite at low temperatures (T similar to 140 K) with high resolution electron 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 > 1280 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. © 1998 Elsevier Science B.V.
