Although metallocenes show great potential as novel Chemical Vapor Deposition (CVD) source molecules, very little is known about how they bond to metal surfaces. Therefore, systematic investigation of ferrocene adsorption to different single crystal substrates are essential for understanding and controlling CVD processes involving metallocenes. We have used HREELS and XPS to study ferrocene, Fe(C@sub 5@H@sub 5@)@sub 2@, deuterated ferrocene, Fe(C@sub 5@D@sub 5@)@sub 2@, and its methylated derivative on Ag(100). HREELS was used to confirm the molecular nature of the adsorbed metallocene, determine the orientation and quantify interactions between ferrocene and the silver substrate. XPS was used to evaluate the chemical state of iron and carbon in the ferrocene films and to quantify the adsorbate surface concentration. Specific information about orientation and chemical shifts as a function of ferrocene exposure will also be presented.
