This book covers the physics and chemistry of surfaces. The scope includes the structure, thermodynamics, and mobility of clean surfaces, as well as the interaction of gas molecules with solid surfaces. The energetic particle interactions that are the basis for the majority of techniques developed to reveal the structure and chemistry of surfaces are explored including auger electron spectroscopy, photoelectron spectroscopy, inelastic scattering of electrons and ions, low energy electron diffraction, scanning probe microscopy, and interfacial segregation. Crystal nucleation and growth are also considered. Principles such as adsorption, desorption and reactions between adsorbates are examined, with coverage also of new developments in the growth of epitaxial, and Langmuir-Blodgett films, as well as treatment of the etching of surfaces. Modern analytical techniques and applications to thin films and nanostructures are included. The latest in-depth research from around the world is presented.
