Book Description
As materials research focuses into finding ways to control the growth of atomic scale structures, there is correspondingly increasing emphasis on to the problem of surface diffusion. Clearly surface diffusion is the key process, which determines how atoms move on the surface. Controlling this motion can lead to the easy fabrication of well-controlled nanostructures broadening the present possibilities in nanotechnology. The paradigm of surface diffusion has outgrown its standard textbook description as a random walk on a rigid substrate. In real systems for more complex situations are encountered: interacting atoms are commonly present on the surface with their motions highly correlated, different phases form on the surface with different dynamics, large concentration gradients drive the system far away from the linear response regime, rich metastable structures form as a result of balanced interplay between different kinetic processes, substrate relaxation can change the energy landscape and the diffusion barriers, etc. The motivation behind this ARW was to bring together the international community working on these problems. We felt that the large number of researchers, new results, and well-formulated open questions in this area require some form of integration in a single forum. The ARW and the upcoming proceedings book with papers by the majority of the participants has provided this forum. The meeting was not planned as a continuation of the earlier NATO ASI in Rhodes in 1996, although several people have participated in both meetings.

Book Description
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.

Book Description
'The book is well organized and is pedagogical. By discussing crystallization in pure systems, the author introduces and describes the important concepts, physical parameters and theoretical models pertaining to nucleation and growth of crystals … If you are a young investigator or a graduate student whose research involves understanding the fundamentals of crystallization including nucleation and growth, this book will be a treat for you. Readers who have a strong background in physical chemistry or thermal physics may find the book easy to read. Nevertheless, this book should be a good reference to have on the bookshelf if you are an experienced researcher whose interest crosses the path with the general topics of crystal growth.'Acta Crystallographica Section BThe processes of new phase formation and growth are of fundamental importance in numerous rapidly developing scientific fields such as modern materials science, micro- and optoelectronics, and environmental science. Crystal Growth for Beginners combines the depth of information in monographs, with the thorough analysis of review papers, and presents the resulting content at a level understandable by beginners in science. The book covers, in practice, all fundamental questions and aspects of nucleation, crystal growth, and epitaxy.This book is a non-eclectic presentation of this interdisciplinary topic in materials science. The third edition brings existing chapters up to date, and includes new chapters on the growth of nanowires by the vapor-liquid-solid mechanism, as well as illustrated short biographical texts about the scientists who introduced the basic ideas and concepts into the fields of nucleation, crystal growth and epitaxy. All formulae and equations are illustrated by examples that are of technological importance. The book presents not only the fundamentals but also the state of the art in the subject.Crystal Growth for Beginners is a valuable reference for both graduate students and researchers in materials science. The reader is required to possess some basic knowledge of mathematics, physics and thermodynamics.

Book Description
This is the first-ever textbook on the fundamentals of nucleation, crystal growth and epitaxy. It has been written from a unified point of view and is thus a non-eclectic presentation of this interdisciplinary topic in materials science. The reader is required to possess some basic knowledge of mathematics and physics. All formulae and equations are accompanied by examples that are of technological importance. The book presents not only the fundamentals but also the state of the art in the subject. The second revised edition includes two separate chapters dealing with the effect of the Ehrlich-Schwoebel barrier for down-step diffusion, as well as the effect of surface active species, on the morphology of the growing surfaces. In addition, many other chapters are updated accordingly. Thus, it serves as a valuable reference book for both graduate students and researchers in materials science. Sample Chapter(s). Crystal-Ambient Phase Equilibrium (396 KB). Contents: Crystal OCo Ambient Phase Equilibrium; Nucleation; Crystal Growth; Epitaxial Growth. Readership: Graduate students, academics and researchers in materials engineering, microelectronics, new materials, semiconductors and related areas."
