The Structure and Electronic Configuration of Crystalline Surfaces
Before the discussion of surface phenomena in terms of electron and structural configurations, some of the reasons for the difficulties associated with a quantitative understanding of surface phenomena, based on theoretical and experimental facts, should be pointed out. In considering a solid surface, one must recognize it as the abrupt termination of the periodic crystalline lattice. In this fact must reside the answers to the many questions that are raised: From the statistical point of view, what happens to the electrons at the termination of the periodic potential? From the atomistic point of view, what happens to the bonding of surface atoms which now have unsaturated forces? From the structural point of view, what are the surface or structural rearrangements that must take place to accommodate the unsaturated forces on the surface?
