Serving as a general introduction to surface and interface science, this book focuses on essential concepts rather than specific details, on intuitive understanding rather than learning facts. The text reflects the fact that the physics and chemistry of surfaces is a diverse field of research and shows this in its Interdisciplinary conceptual design. Once the most important techniques and methods have been introduced, readers will be able to apply simple models to their own scientific problems. Furthermore, manifold high-end technological applications from surface technology, biotechnology, or microelectronics illustrate the basic scientific treatment. The authors address advanced students of chemistry, physics, materials science, chemical engineering and related subjects with a basic knowledge of natural sciences and mathematics, since the mathematical calculations are thoroughly explained and made comprehensible for the reader. As such, non-specialists in surface science who want to learn more about this important subject will also benefit from the book.
