Book Description
This book gives a representative survey of the state of the art of research on gas-surface interactions. It provides an overview of the current understanding of gas surface dynamics and, in particular, of the reactive and non-reactive processes of atoms and small molecules at surfaces. Leading scientists in the field, both from the theoretical and the experimental sides, write in this book about their most recent advances. Surface science grew as an interdisciplinary research area over the last decades, mostly because of new experimental technologies (ultra-high vacuum, for instance), as well as because of a novel paradigm, the ‘surface science’ approach. The book describes the second transformation which is now taking place pushed by the availability of powerful quantum-mechanical theoretical methods implemented numerically. In the book, experiment and theory progress hand in hand with an unprecedented degree of accuracy and control. The book presents how modern surface science targets the atomic-level understanding of physical and chemical processes at surfaces, with particular emphasis on dynamical aspects. This book is a reference in the field.
Introduction to Molecular Beams Gas Dynamics

Pages : 404
Book Description
Introduction to Molecular Beams Gas Dynamics is devoted to the theory and phenomenology of supersonic molecular beams. The book describes the main physical idea and mathematical methods of the gas dynamics of molecular beams, while the detailed derivation of results and equations is accompanied by an explanation of their physical meaning. Many of the applications of supersonic molecular beams are discussed, including their application to molecular spectroscopy, and the study of surface phonons by monoatomic and monokinetic beams, and the study of intermolecular potentials and the onset of condensation. The phenomenology of supersonic beams can appear complex to those not experienced in supersonic gas dynamics and, as a result, the few existing reviews on the topic generally assume a limited level of knowledge. The book begins with a quantitative description of the fundamental laws of gas dynamics and goes on to explain such phenomena. It analyzes the evolution of the gas jet from the continuum to the regime of almost free collisions between molecules, and includes numerous figures, illustrations, tables and references.

Book Description
Molecular beam scattering techniques have firmly established themselves among the major tools for studying the kinetics and dynamics of gas- surface interactions. They have also proven themselves to be of great use in materials synthesis, most notably being used for the molecular beam epitaxial (MBE) growth of semiconductor substrates and superlattices. During the past few years our research group has been very active in developing new and quite general molecular beam techniques for studying the kinetic mechanisms of surface chemical reactions. We have, in particular, focused much of our attention on extending traditional molecular beam measurements to allow us to routinely explore coverage dependent kinetic mechanisms under essentially linearized conditions. These efforts have been quite successful. Our three molecular beam scattering arrangement is unique in the world, and significantly expands the range and power of modulated beam reactive scattering for studying complex kinetics at surfaces. The experimental methodology we have developed utilizes two continuous, independently adjustable beams to establish a desired steady state surface concentration, while a weaker modulated third beam induces small concentration perturbations around the selected steady state. This linearized approach permits the coupled differential equations which represent the overall surface reaction mechanism to be solved perturbatively, yielding quantitative information about the various kinetic steps which comprise overall reaction mechanisms.

Book Description
This instrumentation grant was used to procure several pieces of equipment with significantly enhanced research capabilities for studying the interactions of molecular beams and laser radiation with well defined surfaces in an ultra-high vacuum environment. A partial listing of the topics that are being explored in greater as a direct result of the new instrumentation includes surface phonon spectroscopy, the dynamics and energetics of heterogeneous interactions, thin film growth including nucleation in two-dimensional systems, gas surface energy transfer interaction potentials, and a variety of laser surface processes such surface photochemistry (radical reactions, desorption, ablation), energy transfer, and photoemission.
