Available in PDF, EPUB and Kindle. Book excerpt: Dynamics of Gas-Surface Scattering deals with the dynamics of scattering as inferred from known properties of gases and solids. This book discusses measurements of spatial distributions of scattered atomic and molecular streams, and of the energy and momentum which gas particles exchange at solid surfaces. It also considers two regimes of scattering, both of which are associated with a lower range of incident gas energies: the thermal and structure scattering regimes. Comprised of 10 chapters, this book opens with a brief historical overview of the early experiments that investigated the dynamics of scattering of gases by surfaces. The discussion then turns to some elements of the kinetic theory of gases; intermodular potentials and interaction regimes; and classical-mechanical lattice models used in gas-surface scattering theory. The applications of molecular beams to the study of gas-surface scattering phenomena are also described. The remaining chapters focus on experiments and theories on scattering of molecular streams by surfaces of solids, with emphasis on thermal and structure regimes of inelastic scattering; quantum theory of gas-surface scattering; and quantum mechanical scattering phenomena. This text concludes with an analysis of energy exchange processes that may occur when a solid surface is completely immersed in a still gas. This monograph will be a valuable resource for students and practitioners of physics, chemistry, and applied mathematics.

This book was released on 2013-02-26 with total page 439 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Book excerpt: This research initiative deals with the interaction of neutral particle, electron, and optical beams with well-characterized single crystal surfaces. These studies are motivated by a desire to understand and control surface reactions, such as surface oxidation, the technological need to characterize the physical properties of thin films and surfaces, and the desire to understand how energy and momentum are exchanged at the surface of a material when it is subjected to gas-surface collisions, electron-surface collisions, optical illumination, or chemical reaction. Experiments aimed at determining the surface phonon dispersion relations for a variety of clean and adsorbate covered systems play a central role in this program. Such measurements are crucial for elucidating how the force constants at the surface differ from those characteristic of the bulk for a given material, and how adsorption of atomic and molecular species modify the force constants, and hence electron density distributions, at and in the vicinity of the surface. The experimental program utilizes two, now fully operational, scattering laboratories that were constructed with significant DoD funding. One of these is a high resolution (energy and momentum) neutral particle scattering apparatus which routinely carries out single phonon inelastic as well as diffractive scattering measurements. The other laboratory houses an inelastic electron scattering instrument which also produces momentum-resolved inelastic scattering data. The capabilities of these two facilities complement each other in many important and useful ways.

This book was released on 1995-03-22 with total page 140 pages. Available in PDF, EPUB and Kindle. Book excerpt: Interface phenomena are most fascinating because of the mixing of different scales and the interference of diverse physical processes. This makes it necessary to use different levels of description: microscopic, kinetic, and gas-dynamical. A unified quasiclassical approach is used to answer practical questions dealing with inelastic gas-surface scattering, the kinetics of adsorption layers, the evolution of inhomogeneities and defects at the surface, the Knudsen layer, the development of boundary conditions on the kinetic and gas-dynamical levels, the determination of exchange and slip coefficients, and so on.

Available in PDF, EPUB and Kindle. Book excerpt: Helium and molecular hydrogen scattering from copper is calculated to examine general features of scattering for these systems, especially the quantum mechanics of the scattering process, both for the motion of the particle and the excitations of the lattice. These calculations use an interaction potential chosen to simplify the numerical calculation while retaining the essential physics of the interaction. The scattering calculations show that these approximations quantitatively reproduce experimental results. The scattering probabilities are shown to depend on details of the system like the well depth and the steepness of the potential and assumptions are made to simplify the interaction potential. H2 and D2 inelastic scattering and trapping probabilities show strong enhancement by selecti adsorption resonances and overall changes in scattering intensities due to other more subtle effects of the rotational degrees of freedom. Temperature dependent HD scattering probabilities show the effect of inelastic scattering on rotationally inelastic scattering and selective adsorption resonances.
Download or read book Heterogeneous Reaction Dynamics written by S. Bernasek and published by John Wiley & Sons. This book was released on 1995-10-12 with total page 186 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is an in-depth monograph covering the topic of energy transfer and reactions on solid surfaces. This topic is of great interest now because of its applications to catalysis and solid-state electronics, including the manufacture of semiconductors, integrated circuits and other solid state devices. Initially it describes what is meant by heterogenous reaction dynamics. Basically, this is the study, on a molecular level, of the elementary dynamics of energy transfer and reactions at surface. The emphasis of the book will be on well characterized solid surfaces. Energy transfer and reactions are broadly defined to include phase transitions in adsorbed layers, diffusion, the absorption process itself, and energy transfer between adsorbate and subtrate, as well as gas-surface energy transfer, catalytic and oxidative type surface reactions.

Available in PDF, EPUB and Kindle. Book excerpt: A method is presented for calculating elastic and inelastic scattering probabilities for light particles, such as helium and molecular hydrogen, scattering from surfaces with which they weakly interact. The method is a unitary one-phonon approximation in which the scattering probabilities are calculated from thermally averages amplitudes which are generated numerically. The thermal averaging procedure is more general than this application and could be applied to other systems with weak inelastic scattering. An approximation for the gas surface interaction potential is discussed that can greatly simplify calculations where it is applicable. Finally some preliminary results are presented using this method to study rotationally mediated selective adsorption resonances in HD scattering from copper.
