Adsorbate Structure and Adsorbate-Induced Restructuring at Metal Surfaces... 

Tabulations of some surface structures may be found in a review by Van Hove and coworkers (Van Hove et al., 1989) and the reviews by Watson that compare the results of surface structure determinations utilizing different crystallographic techniques (Watson, 1990, 1992). Van Hove has also published a recent review of crystal surface structure, without the tabular presentation of the structural data (Van Hove, 1992). Van Hove and Somorjai have reviewed surface structure from the point-of-view of adsorbate induced restructuring of surfaces (Van Hove and Somorjai, 1989). Ohtani and coworkers have listed all observed overlayer structures and surface symmetries, albeit without any reference to the detailed surface structure (Ohtani et al., 1987).

Defect sites (steps or kinks) and rough, low-packing-density surfaces have higher charge densities near the Fermi level. This is shown by lower work functions and the higher densities of filled electronic states detected by photoemission studies. These rough surfaces restructure more readily when clean, as described in Chapter 2. They are likely to participate in more massive adsorbate-induced restructuring... 

Adsorbate-induced restructuring of surfaces could explain the formation of cluster-like bonding of adsorbates on metal surfaces. Discuss how the strength of the chemisorption bond is likely to influence the restructuring of metal surfaces. 

The work of adhesion is also related to the force needed to break chemical bonds at the interface on the atomic scale. When bonds form at the interface of two solids, restructuring can occur at both sides of the interface, thereby optimizing the strength of the interfacial chemical bond. This restructuring is related to the adsorbate-induced restructuring processes and to the phenomenon of epitaxy that was discussed in Chapters 2 and 5. It involves the movement of atoms perpendicular, as well as parallel, to the interface. We may call this movement the work of interface restructuring It involves surface atoms as well as atoms two to three layers away from... 

Adsorbate Induced Restructuring. Perhaps, the most striking observation of recent years is the adsorbate induced restructuring of surfaces. This can be demonstrated by the restructuring of the nickel (100) face(13) in the presence of half a monolayer of carbon...
