Electronic Properties of Surfaces
The concept of a surface state is discussed in terms of trapping by repeated reflection from the crystal and surface barrier. Surface states play the role of “dangling bonds” on semiconductors but not on metals. The notion of incomplete orbitals is introduced in the context of bonding to metal surfaces. Finally an extended discussion is made of photoemission, its information content and surface sensitivity, several examples being presented.
