Abstract:
This dissertation describes experimental investigations of deposited atomic clusters and of films of metal particles produced by cluster deposition on graphite. It consists of three chapters presenting a review of the addressed subjects, the experimental techniques, and a summary of the results. The main body of results is described in full in afourth chapter as research papers. A systematic study of the impact of metal cluster trimers on highly oriented pyrolitic graphite (HOPG) is investigated. The creation of defects at the surface of graphite is found to be independento f the masso f the atoms in the two typeso f clusters considered The electron energy loss spectroscopy (EELS) of collective electronic excitations (plasmons) in a film of silver particles is presented A weak positive dispersion of the plasmon mode is measured and exhibits a higher ftequency of the mode with parallel momentum close to zero than in Ag surfaces. The adsorption of cinnamaldehydeis examined on nanostructured palladium surfaces. The EELS spectrum of cinnamaldehyde adsorbed on palladium is presented, as well as that of condensed layers of cinnamaldehyde on HOPG. Findings of this thesis involve different physical and chemical properties of the cluster surface system with a view in using cluster deposition for practical applications such as the investigation of model catalysts.
