Bonding and Interaction of Atoms and Molecules on Single Crystal Surfaces

Abstract

The study of atomic and molecular adsorption on well-defined metal surfaces is of crucial importance to the understanding of many technologically important processes such as thin film growth, catalysis, corrosion, and the rates of chemical reactions on surfaces. The experimental methods employed in this study include the field ion microscope (FIM) and hyperfine interaction techniques. The systems chosen for study included the adsorption of hafnium and cadmium atoms on single crystal surfaces of tungsten and nickel. The choice of experimental techniques and systems for this study was dictated by a desire to evaluate hyperfine interaction techniques for the study of surface adsorption, through comparison with the results obtained by the now well established FIM technique for the study of surface adsorption.
