The Chemistry and Physics of Solid Surfaces volumes present selected review articles, mainly in the area of the solid-gas interface. These articles are written by internationally recognized experts who are invited speakers at the International Summer Institute in Surface Science. Volume VII includes, among others, the following topics: Inert Gas Layers on Metal Surfaces, Infrared Spectroscopy of Semiconductor Surfaces, Critical Phenomena of Chemisorbed Atoms, NEXAFS and SEXAFS, Surface Reconstruction, Scanning Tunnelling Microscopy, Fractals in Surface Science, Growth Kinetics in Molecular Beam Epitaxy. It is the purpose of these volumes to bring researchers in academia and industry up to date and to bridge the gap between conventional textbooks and specialized surface science conference proceedings. The volumes provide extensive references to the literature and each includes a detailed subject index.
