Synopsis

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.

Synopsis

The book includes articles by leading experts in the field of surface diffusion discussing recent experimental and theoretical developments of the problem. The emphasis is on the study of surface diffusion when many mutually interacting atoms are present on the surface. Such interactions between atoms result in correlations in their motion. By measuring surface diffusion coefficients as a function of temperature, atom concentration, initial atom configuration, etc., the energy barriers of the diffusing atoms can be extracted. Theoretical analysis is used to develop a better understanding and predictability of how diffusion barriers vary from system to system. Most of the articles in the book present the state of the art in the field i.e. how to measure and how to understand the dependence of the diffusion coefficient on different physical parameters (coverage, temperature, region of the phase diagram etc.) in different experimental systems. The book is nicely balanced between theoretical and experimental articles. It will interest physicists, chemists, materials scientists working in the area of growth of new materials.

Although its main emphasis is on understanding fundamental questions about the diffusion of atoms on surfaces, it will also interest people working in more applied aspects to produce atomic scale structures.
