Abstract

Clean low-index single crystal surfaces of pure metals and ordered arrangements of adsorbed atoms and molecules on such surfaces constitute a most important class of idealized systems from which we expect to derive basic understanding about interactions in the surface region of metals. Even in the case of such simple systems at stationary state our present knowledge of conventional physical observables in solid state and molecular physics e.g. atomic arrangement, atomic vibrations and electron structure is relatively limited. This is so for experimental as well as for theoretical reasons. The surface region being an inhomogenity of matter is complicated to investigate experimentally comprising accurate control of a stationary state, sensitive measuring techniques and unfolding of surface and bulk information. Similarly the inhomogenity causing break-down of three-dimensional translational periodicity forces, in many cases, theoretical considerations of a formidable molecular problem encompassing a great number of atoms to be considered in order to account for the underlying bulk crystal.
