Eine allgemeine und dennoch ausführliche Einführung in die Oberflächen- und Grenzflächenphysik. Der Text spiegelt die Vielseitigkeit dieses Fachgebietes wieder, indem thermodynamische Grundlagen mit ingenieurwissenschaftlichen Themen wie Benetzung von Oberflächen, Reibung und Schmierung verknüpft werden. Die vorgestellte Theorie wird durch die Beschreibung von Verfahren und Anwendungen in Oberflächen- und Biotechnologie sowie in der Mikroelektronik beispielhaft illustriert.
Das Werk richtet sich an Studenten der Physik, Chemie und der Materialwissenschaften in den höheren Semestern und eignet sich gleichwohl als Einführung für Ingenieure und Wissenschaftler.

Autorentext
Hans-Jürgen Butt studied physics at the Universities of Hamburg and Göttingen, Germany. Then he went to the Max-Planck-Institute of Biophysics in Frankfurt. After receiving his Ph.D. in 1989 he went as a postdoc to Santa Barbara, California, and learned using the newly developed atomic force microscope. From 1990-95 he spent as a researcher back in Germany at the Max-Planck-Institute for Biophysics. In 1996 he became associate professor at the University of Mainz. Three years later he moved to Siegen to become full professor for physical chemistry. Only two years later he joined the Max-Planck-Institute of Polymer Research in Mainz. Karlheinz Graf studied chemistry at the universities of Erlangen and Mainz, Germany. After receiving his Ph.D. in Physical Chemistry in 1997, he went as a postdoc to Santa Barbara, California working on physicochemical aspects of myelin and lung surfactant. Back in Mainz he investigated nanostructured lipopolymer films. Scince 2001 he is working on model systems for microsystem technology in the group of Prof. Hans-Jürgen Butt at the Max-Planck-Institut for Polymer Research and the University of Siegen.

Michael Kappl studied physics at the University of Regensburg and the Technical University of Munich. He finished his PhD at the Max-Planck-Institute of Biophysics in Frankfurt/Main in 1996. From 1997 - 1998 he did one and a half years of postdoctoral research at the University of Mainz in the group of Prof. Butt. From 1998-2000 he worked as a IT consultant at Pallas Soft AG, Regensburg. In 2000, he rejoined the group of Prof. Butt at the University of Siegen. Since end of 2002 he is project leader at the MPI for Polymer research in Mainz.

Klappentext
Serving as a general introduction to surface and interface science, this book focuses on basic concepts rather than specific details, on intuitive understanding rather than learning facts. The text reflects that physics and chemistry of surfaces is a diverse field of research which involves classical scientific and engineering disciplines. Fundamentals subject like thermodynamics of interfaces as well as applied topics such as wetting, friction, and lubrication are discussed. The most important techniques and methods are introduced. Readers will be able to apply simple models to their own scientific problems. Furthermore, manifold high end technological applications are shown parallel with the basic scientific treatment, e.g. AFM, surface technology, biotechnology, microelectronics, biomaterials.

The authors address advanced students of chemistry, physics, materials science, chemical engineering and related subjects with a basic knowledge of natural sciences and mathematics. Also scientists and engineers who are not yet specialists in surface science but want to learn more about this important subject will benefit from the book.
