Available in PDF, EPUB and Kindle. Book excerpt: The interest in the problem of surface diffusion has been steadily growing over the last fifteen years. This is clearly evident from the increase in the number of papers dealing with the problem, the development of new experimental techniques, and the specialized sessions focusing on diffusion in national and international meetings. Part of the driving force behind this increasing activity is our recently acquired ability to observe and possibly control atomic scale phenomena. It is now possible to look selectively at individual atomistic processes and to determine their relative importance during growth and reactions at surfaces. The number of researchers interested in this problem also has been growing steadily which generates the need for a good reference source to farniliarize newcomers to the problem. While the recent emphasis is on the role of diffusion during growth, there is also continuing progress on the more traditional aspects of the problem describing mass transport in an ensemble of particles. Such a description is based on the statistical mechanical analysis of a collection of particles that mutually interact and develop correlations. An average over the multitude of atomistic processes that operate under these conditions is necessary to fully describe the dynamics in the system.

This book was released on 2012-09-02 with total page 139 pages. Available in PDF, EPUB and Kindle. Book excerpt: The hydrogen bond represents an important interaction between molecules, and the dynamics of hydrogen bonds in water create an ever-present question associated with the process of chemical and biological reactions. In spite of numerous studies, the process remains poorly understood at the microscopic level because hydrogen-bond dynamics, such as bond rearrangements and hydrogen/proton transfer reactions, are extremely difficult to probe. Those studies have been carried out by means of spectroscopic methods where the signal stems from the ensemble of a system and the hydrogen-bond dynamics were inferred indirectly. This book addresses the direct imaging of hydrogen-bond dynamics within water-based model systems assembled on a metal surface, using a scanning tunneling microscope (STM). The dynamics of individual hydrogen bonds in water clusters, hydroxyl clusters, and water-hydroxyl complexes are investigated in conjunction with density functional theory. In these model systems, quantum dynamics of hydrogen bonds, such as tunneling and zero-point nuclear motion, are observed in real space. Most notably, hydrogen atom relay reactions, which are frequently invoked across many fields of chemistry, are visualized and controlled by STM. This work presents a means of studying hydrogen-bond dynamics at the single-molecule level, providing an important contribution to wide fields beyond surface chemistry.

Available in PDF, EPUB and Kindle. Book excerpt: Surfaces and Interfaces: Physics and Electronics covers the proceedings of the second Trieste ICTP-IUPAP Semiconductor Symposium, conducted at the International Center for Theoretical Physics in Trieste, Italy on August 30 to September 3, 1982. The book focuses on the processes, methodologies, reactions, and approaches involved in semiconductor physics. The selection first elaborates on the electronic properties and surface geometry of GaAs and ZnO surfaces; electronic structure of Si (III) surfaces; and photoemission studies of surface states on Si (III) 2X1. Discussions focus on consistency of different experiments, relating experiments to a theoretical model, quenching of surface states by hydrogen, inverse photoemission results, and basic data and models of the low-index ZnO surfaces. The text then examines Si (III) 2X1 studies by angle resolved photoemission; electronic surface states at steps in Si (III) 2X1; and a novel method for the study of optical properties of surfaces. The manuscript takes a look at spot profile analysis (LEED) of defects at silicon surfaces; chemisorption-induced defects at interfaces on compound semiconductors; and surface defects on semiconductors. The microscopic properties and behavior of silicide interfaces, recombination at semiconductor surfaces and interfaces, and dipoles, defects, and interfaces are also discussed. The selection is a highly recommended source of data for physicists and readers wanting to study semiconductor physics.

Download or read book Phase Transitions and Adsorbate Restructuring at Metal Surface written by D.A. King and published by Newnes. This book was released on 2012-12-02 with total page 660 pages. Available in PDF, EPUB and Kindle. Book excerpt: The objective in initiating this series in 1980 was to provide an in-depth review of advances made in the understanding key aspects of surface chemistry and physics through the application of new techniques to the study of well-defined surfaces. Since then the field of surface science has greatly matured, and further important techniques, particularly scanning probe microscopies, have been successfully assimilated into the applications armoury of the surface scientist. The present volume is a series of timely reviews by many of the current experts in the field of phase transitions and adsorbate-induced surface restructuring. No aspect of the science of solid surfaces can be fully understood without accounting for the structural diversity of surfaces, now revealed in atomic detail by techniques based on diffraction and scanning probe microscopies. For example, it is now clear to those working in heterogeneous catalysis that adsorbate-induced restructuring of surfaces can play a critical role in phenomena such as bistability, kinetic oscillations, and promotion and poisoning. Structural transitions at surfaces can also play a key role in determining the electronic properties of surfaces, reviewed in volume 5.

Download or read book Chemistry and Physics of Solid Surfaces VIII written by Ralf Vanselow and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 471 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume contains review articles written by the invited speakers at the ninth International Summer Institute in Surface Science (ISISS 1989), held at the Uni versity of Wisconsin-Milwaukee in August of 1989. During the course of ISISS, invited speakers, all internationally recognized experts in the various fields of surface science, present tutorial review lectures. In addition, these experts are asked to write review articles on their lecture topic. Former ISISS speakers serve as advisors concerning the selection of speakers and lecture topics. Emphasis is given to those areas which have not been covered in depth by recent Summer Institutes, as well as to areas which have recently gained in significance and in which important progress has been made. Because of space limitations, no individual volume of Chemistry and Physics of Solid Surfaces can possibly cover the whole area of modern surface science, or even give a complete survey of recent progress in this field. However, an attempt is made to present a balanced overview in the series as a whole. With its comprehensive literature references and extensive subject indices, this series has become a valuable resource for experts and students alike. The collected articles, which stress particularly the gas-solid interface, have been published under the following titles: Surface Science: Recent Progress and Perspectives, Crit. Rev. Solid State Sci.

Download or read book Metal Ceramic Interfaces written by M. Rühle and published by Elsevier. This book was released on 2013-10-22 with total page 448 pages. Available in PDF, EPUB and Kindle. Book excerpt: As engineering materials and structures often contain a metal or metallic alloy bonded to a ceramic, the resultant interface must be able to sustain mechanical forces without failure. They also play an important role in oxidation or reduction of materials. The workshop on 'Bonding, Structure and Mechanical Properties of Metal/Ceramic Interfaces' was held in January 1989 within the Acta/Scripta Metallurgica conference series. It drew together an international collection of 70 scientists who discussed a wide range of issues related to metal-ceramic interfaces. The sessions were divided into 7 categories: structure and bonding, chemistry at interfaces, formation of interfaces, structure of interfaces, thermodynamics/atomistics of interface fracture, mechanics of interface cracks, and fracture resistance of bimaterial interfaces. Within these headings attention was paid to grain boundaries, the influence of chemical processes on the behaviour of interfaces, diffusion bonding, characterization of fracture, and crack propagation by fatigue and by stress corrosion. The book presents a useful reference source for materials scientists, physicists, chemists, and mechanical engineers who are concerned with the roles and properties of interfaces.

Download or read book International Symposium on Structure and Dynamics of Heterogeneous Systems written by Peter Entel and published by World Scientific. This book was released on 2000 with total page 366 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume contains contributions from co-operative research activities in physics and chemistry and addresses heterogeneous systems like atoms and molecules in complex environments, dye molecules like the retinal chromophore in the protein box of the human eye, interacting atoms/molecules in the interlayer of adsorbed structures, nucleation and domain formation processes in magnetic and martensitic systems. The particular aim of the contributions is to deduce the connection between different grades of heterogeneity and to bridge the gap between chemicals and heterogeneity on the atomic scale, and the physics of macroscopically heterogeneous systems. Besides the diverse experimental tools employed in the investigations, accompanying theoretical investigations range from ab initio molecular dynamics studies of the microscopic systems to Monte Carlo simulations of the larger-scale problems.

Download or read book Physics and Chemistry of Small Clusters written by P. Jena and published by Springer Science & Business Media. This book was released on 2013-06-29 with total page 932 pages. Available in PDF, EPUB and Kindle. Book excerpt: Recent advances in experimental techniques now enable researchers to produce in a laboratory clusters of atoms of desired composition from any of the elements of the periodic table. This has created a new area of research into novel materials since clusters cannot be regarded either as a "large" molecule or as a fragment of the bulk. Both experimental and theoretical studies are revealing unusual properties that are not ob served in solid state environments. The structures of micro-clusters are found to be significantly distorted from the most symmetric arrangement, some even exhibiting pentagonal symmetry commonly found in icosahedric structures. The unusual stability of certain clusters, now described as "magic number species", shows striking similarities with the nuclear shell structure. The relative stabilities of clusters depend not only on the composition of the clusters but also on their charged states. The studies on spontaneous fragmentation of mUltiply charged clusters, commonly referred to as Coulomb explosion, illustrate the role of electronic bonding mechanisms on stability of clusters. The effect of foreign atoms on geometry and stability of clusters and the interaction of gas atoms with clusters are showing promise for an indepth understanding of chemisorption and catalysis. The magnetic and optical properties are dependent not only on cluster size but also on its geometry. These findings have the potential for aiding industry in the area of micro-electronics and catalysis.

Download or read book Treatise on Solid State Chemistry written by N. Hannay and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 501 pages. Available in PDF, EPUB and Kindle. Book excerpt: The last quarter-century has been marked by the extremely rapid growth of the solid-state sciences. They include what is now the largest subfield of physics, and the materials engineering sciences have likewise flourished. And, playing an active role throughout this vast area of science and engineer ing have been very large numbers of chemists. Yet, even though the role of chemistry in the solid-state sciences has been a vital one and the solid-state sciences have, in turn, made enormous contributions to chemical thought, solid-state chemistry has not been recognized by the general body of chemists as a major subfield of chemistry. Solid-state chemistry is not even well defined as to content. Some, for example, would have it include only the quantum chemistry of solids and would reject thermodynamics and phase equilibria; this is nonsense. Solid-state chemistry has many facets, and one of the purposes of this Treatise is to help define the field. Perhaps the most general characteristic of solid-state chemistry, and one which helps differentiate it from solid-state physics, is its focus on the chemical composition and atomic configuration of real solids and on the relationship of composition and structure to the chemical and physical properties of the solid. Real solids are usually extremely complex and exhibit almost infinite variety in their compositional and structural features.
