A subject of keen scientific inquiry since the last century, surface physics emerged as an independent discipline only in the late 1960s resulting from the development of ultra-high vacuum technology and high speed digital computers. With these tools, reliable experimental measurements and theoretical calculations could at last be compared. Physics at Surfaces is a unique introduction to the physics and chemical physics of solid surfaces, and atoms and molecules that interact with solid surfaces. This book provides a synthesis of the entire field of surface physics from the perspective of a modern condensed matter physicist with a healthy interest in chemical physics.Preface; List of acronyms; Historical sketch; Part I.
