Book Description
Surface crystallography is a discipline which has come of age. There exist in the literature several hundred complete determinations of atomic configurations at surfaces: yet the number is not so great that cataloguing these structures is too daunting a task. We felt that now was the right moment to begin a compilation that could be updated at frequent intervals to give a comprehensive picture of the known surface world. The following pages are the product of our labours. Our target community is the large number of surface chemists, materials scientists, physicists and others whose work involves surfaces. As the compilation expands with time our hope is that it will become one of the standard reference works for structures: in the manner that Wyckoff and other X-ray tables are for bulk crystals. We have devoted considerable thought to the format. The system we have chosen will no doubt have its critics, and in subsequent editions may well be improved, but it has been arrived at after extensive consultation. A problem that we faced in putting structures into standard format was the diversity of conventions used in the literature. It is to be hoped that our system will have sufficient virtue to serve as a standard format for future reporting of structures. That would make it much easier for surface crystallographers to use the work of others.

Book Description
In den Oberflächen- und Nanowissenschaften ist ein fundiertes Verständnis lokaler Geometrie und Symmetrie von Kristallen und deren Oberflächen von entscheidender Bedeutung, da die Kristallstruktur viele physikalische und chemische Parameter mitbestimmt. Studenten und Forscher in Physik, Chemie und Materialwissenschaften erhalten hierzu mit dem vorliegenden Buch sowohl eine wertvolle Einführung wie auch ein nützliches Nachschlagewerk. Das Buch führt insbesondere scheinbar disparate Beschreibungen und Notationen zusammen, die ständig von Oberflächen- und Nanowissenschaftlern benötigt werden. Professor Hermann ist als Wissenschaftler im Bereich der theoretischen Oberflächenphysik ausgewiesen und bekannt als Koautor der NIST Surface Structure Database (SSD), einer absoluten Referenz in der Struktur- und Oberflächenwissenschaft. Seine Arbeiten zur Oberflächenvisualisierung dokumentiert er auch in diesem Buch, in dem aufwändige Grafiken der zahlreichen Beispiele die mathematisch formal gewählte Herangehensweise illustrieren. Übungen mit unterschiedlichem Schwierigkeitsgrad - von einfachen Fragen bis zu kleinen Forschungsprojekten - regen die Diskussion zu den unterschiedlichen Themen an.

Book Description
It is almost self-evident that surface and interface science, coupled with the electronic structure of bulk materials, playa fundamental role in the understanding of materials properties. If one is to have any hope of understanding such properties as catalysis, microelectronic devices and contacts, wear, lubrication, resistance to corrosion, ductility, creep, intragranular fracture, toughness and strength of steels, adhesion of protective oxide scales, and the mechanical properties of ceramics, one must address a rather complex problem involving a number of fundamental parameters: the atomic and electronic structure, the energy and chemistry of surface and interface regions, diffusion along and across interfaces, and the response of an interface to stress. The intense need to gain an understanding of the properties of surfaces and interfaces is amply attested to by the large number of conferences and workshops held on surface and interface science. Because of this need, the fields of surface and interface science have been established in their own right, although their development presently lags behind that of general materials science associated with bulk, translationally invariant systems. There are good reasons to expect this situation to change rather dramatically in the next few years. Existing techniques for investigating surfaces and interfaces have reached maturity and are increasingly being applied to systems of practical relevance. New techniques are still being created, which drastically widen the scope of applicability of surface and interface studies. On the experimental side, new microscopies are bearing fruit.

Book Description
During the past fifteen years there has been a dramatic increase in the number of different surfaces whose structures have been determined experimentally. For example, whereas in 1979 there were only 25 recorded adsorption structures, to date there are more than 250. This volume is therefore a timely review of the state-of-the-art in this dynamic field.Chapter one contains a compilation of the structural data base on surfaces within a series of tables that allows direct comparison of structural parameters for related systems. Experimental structural trends amongst both clean surfaces and adsorbate systems are highlighted and discussed.The next chapter outlines the successes of local density functional theory in predicting the relaxations and reconstructions of clean metal and semiconductor surfaces, and the behaviour of adsorbates such as hydrogen, oxygen and alkali elements on metal surfaces, thereby explaining some of the experimental trends observed within the database. These ab initio density functional calculations are of ground state properties at the absolute zero of temperature. Chapter three provides an introduction to finite temperature effects in a pedagogical review of current statistical mechanical treatments of phase transitions at surfaces, many of which display the prominent role of fluctuations or non-mean field behaviour. The final chapter discusses the relationship of the reactivity of a surface to its morphology and composition, which is particularly relevant to a fundamental understanding of catalysis.

Book Description
This book contains the proceedings of the NATO Advanced Study Institute on Surfaces and Interfaces of Ceramic Materials, held on the Oleron island, France, in September 1988. This Institute was organized in nine months after receiving the agreement of the NATO Scientific Affairs Division. Despite this very short time, most of the lecturers contacted have accepted our invitation to prepare a specific talk. The meeting was held at "La Vieille Perrotine" on the Oleron island. This holiday village of the French CNRS is located near the Ocean in a natural area which contributed to create a very pleasant atmosphere favourable to develop interaction between the 91 participants in this Institute. First of all, the Institute was aimed at diffusing the foremost results on the characterization of and the role played by surfaces, grain boundaries and interfaces in preparation and overall properties of ceramic materials, mainly of oxide ceramics. Through its interdisciplinary character, the Institute was also aimed at developing interaction between scientists and engineers interested in basic and practical aspects of processing and use of ceramics.

Book Description
Between the area known as surface science (which mainly deals with single crystal surfaces) and the vast area of the surface properties of dispersed solids (knowledge of which is widely applied in catalysis and materials science) there is still a remarkably wide, although gradually decreasing, gap. Because fundamental physico-chemical problems are involved, this borderline area needs to be explored. With this objective, the Trieste meeting brought together specialists with a variety of origins and backgrounds, with the aim of stimulating the growth of our knowledge in this area.This proceedings volume contains ninety-three papers, comprising plenary lectures, short communications, and poster contributions on the applications of physical and theoretical methods to perfect and dispersed (microcrystalline and amorphous) metals, oxides, and mixed systems. Special emphasis is given to metal-support interfaces.The book thus provides a wealth of up-to-date information on a topic of current interest which will be of value to researchers who use chemical and/or physical methods for the study of surfaces.

Book Description
Taking up where the first volume left off, this work provides coverage of the inhomogeneous semiconductor. It deals mainly with Si and GaAs, but also investigates other materials of theoretical and practical interest, such as Ge, other III-V and II-VI compounds, and amorphous SiH. Equipped with this source, physicists, semiconductor engineers, device engineers and fabrication engineers will have access to a vast reservoir of practical information on the design, production and operations of semiconductor devices.
