Concepts in Surface Physics presents a tutorial treatment of the main concepts and phenomena of the physics of crystal surfaces. Emphasis is placed on simplified calculations - and the corresponding detailed analytical derivations - that are able to throw light on the most important physical mechanisms. More rigorous techniques, which often require a large amount of computer time, are also explained. The topics treated include thermodynamic and statistical properties of clean nd adsorbate-covered surfaces, atomic structure, vibrational properties, electronic structure, and the theory...
