Produktbeschreibung

Crystal growth far from thermodynamic equilibrium is nothing but homoepitaxy - thin film growth on a crystalline substrate of the same material. Because of the absence of misfit effects, homoepitaxy is an ideal playground to study growth kinetics in its pure form. Despite its conceptual simplicity, homoepitaxy gives rise to a wide range of patterns. This book explains the formation of such patterns in terms of elementary atomic processes, using the well-studied Pt/Pt(111) system as a reference point and a large number of Scanning Tunneling Microscopy images for visualization. Topics include surface diffusion, nucleation theory, island shapes, mound formation and coarsening, and layer-by-layer growth. A separate chapter is dedicated to describing the main experimental and theoretical methods. The text is aimed at physicists with an interest in growth kinetics, surface scientists, graduate students, and practitioners of thin film deposition.

Autorenporträt

The clear and simple style makes the book to an introduction into the new microscopic world opened by scanning tunneling microscopy for a broader readership. A specific feature is also the experimentally based approach to epitaxial growth. The book is of specific use for students, PhD students and scientists, who want an introduction to the field or intend to become active in the field.
