Applications of surface resistivity to atomic scale friction, to the migration of ‘‘hot’’ adatoms, and to electrochemistry

This work focuses on the concept of surface resistivity. The change in the resistivity of thin metallic films upon adsorption of atoms and molecules is discussed and the resistivity change is related to the nature of the adsorption bond. With this background, I discuss applications to atomic scale friction, surface migration of ‘‘hot’’ adatoms, and electrochemistry.
