This book provides a comprehensive survey of various theoretical/computational models available for simulating energetic collisions of atoms with surfaces. Although the book does not address traditional crystallographic methods, it provides the framework for understanding how experimental techniques such as ion scattering spectroscopy (ISS) are sensitive to surface structure. The nine chapters are well organized, and smooth transitions between the various topics demonstrate the editor's skillful coordination of contributions from seven co-authors. While citing many experimental studies along the way, the book focuses on treating the dynamics of atom/surface collisions through non-experimental methods. The text begins with a review of classical scattering theory and the origins of binary collision theory. Throughout, the authors show with clarity and rigor how various standard equations are derived from first principles. It is not assumed that the reader has an advanced degree in physics or mathematics. The authors survey four basic approaches to modeling dynamics: binary collision theory, transport theory, Monte Carlo techniques, and molecular dynamics simulations. Because an accurate atom/surface potential is required in all computational treatments, a chapter is devoted to the most common semi-empirical methods used for calculating these potentials.

A major theme to the book is understanding the inelastic processes
involved when an energetic ion penetrates a lattice. The authors review
many models which describe both the excitation of electrons in the solid
and the recoil of substrate nuclei brought about by a swift atomic
projectile.
Discussion focuses on predicting the final rest distribution of the
projectiles within the lattice, the corresponding atom displacements
induced in the substrate, and sputtering phenomena. Along the way, the
authors evaluate many of the popular algorithms and computational
packages
used in the field, such as *TRIM*,
*TRIDYN*,
*PRAL*,
*KORAL*,
*VEGAS*,
*MARLOWE* and
*SUSPRE*.
The authors demonstrate how numerical simulations of ISS,
secondary ion mass spectrometry (SIMS), depth profiling, radiation
damage,
and ion implantation can lead to a greater understanding of the
fundamental
dynamics. A chapter is also devoted to simulations of the surface
topographical changes induced by ion bombardment and deposition.
The Editor succeeds in providing a valuable resource for
researchers in academia and industry, in fields of surface science,
semiconductor engineering, thin-film deposition, and particle-surface
interactions, who desire a deeper understanding of the non-experimental
ways to study energetic atom/surface collisions. Although the book does
not include problems for students, it would make an excellent supporting
text for a special topics graduate course. Those interested in
structural
information will find a description of forward simulations whereby
computations accurately reproduce ISS data; however, the inverse
problem,*
i.e.* extracting a unique surface structure directly
from ISS data, has yet to be solved.
