Surface Properties of Electronic Materials is the fifth volume of the series, The Chemical Physics of Solid Surfaces and Heterogeneous Catalysis. This volume indicates the present state of some basic properties of semiconductor surfaces. Chapter one summarizes the general problems in electronic materials and the areas affected by the surface science methods. The next two chapters illustrate the existing perception of the electronic and structural properties of elemental and compound semiconductor surfaces. This volume also deals with the properties of adsorption of semiconductors relating to both relevant gas phase species and metals. Chapters four to six of this volume explore compound semiconductors and elemental semiconductors. The remaining chapters of this volume explore the adsorption of metals on elemental semiconductors; aspects of growth kinetics and dynamics involved in molecular beam epitaxy; molecular beam epitaxy of silicon; insulators; and metastable phases. The last chapter covers the surface chemistry of dry etching processes.

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.

The Chemical Physics of Solid Surfaces, Volume 6: Coadsorption, Promoters, and Poisons focuses on the processes, reactions, and approaches involved in coadsorption and the functions of promoters and poisons in synthesis and reactions. The selection first offers information on adsorbate-adsorbate interactions on metal surfaces and interaction between alkali metal adsorbates and adsorbed molecules. Discussions focus on coadsorption of alkali metals and other molecules; model experiments of catalyst promotion; effective medium theory; direct and indirect hybridization effects; and elastic interaction between adsorbates. The publication then ponders on coadsorption of carbon monoxide and hydrogen on metal surfaces and adsorption on bimetallic surfaces. The manuscript examines the chemical properties of alloy single crystal surfaces and promotion in ammonia synthesis. Topics include substrate dependence of nitrogen adsorption and ammonia synthesis; effects of promotion on nitrogen dissociation and ammonia synthesis; and theoretical modeling. The text then elaborates on promotion in the Fischer-Tropsch hydrocarbon synthesis, promoters and poisons in the water-gas shift reaction, and strong metal-support interactions. The selection is a recommended reference for physicists and readers interested in coadsorption, promoters, and poisons.

Principles of Adsorption and Reaction on Solid Surfaces As with other books in the field, Principles of Adsorption andReaction on Solid Surfaces describes what occurs when gases come incontact with various solid surfaces. But, unlike all the others, italso explains why. While the theory of surface reactions is stillunder active development, the approach Dr. Richard Masel takes inthis book is to outline general principles derived fromthermodynamics and reaction rate theory that can be applied toreactions on surfaces, and to indicate ways in which theseprinciples may be applied. The book also provides a comprehensivetreatment of the latest quantitative surface modeling techniqueswith numerous examples of their use in the fields of chemicalengineering, physical chemistry, and materials science. A valuableworking resource and an excellent graduate-level text, Principlesof Adsorption and Reaction on Solid Surfaces provides readerswith: * A detailed look at the latest advances in understanding andquantifying reactions on surfaces * In-depth reviews of all crucial background material * 40 solved examples illustrating how the methods apply tocatalysis, physical vapor deposition, chemical vapor deposition,electrochemistry, and more * 340 problems and practice exercises * Sample computer programs * Universal plots of many key quantities * Detailed, class-tested derivations to help clarify keyresults The recent development of quantitative techniques for modelingsurface reactions has led to a number of exciting breakthroughs inour understanding of what happens when gases come in contact withsolid surfaces. While many books have appeared describing variousexperimental modeling techniques and the results obtained throughtheir application, until now, there has been no single-volumereference devoted to the fundamental principles governing theprocesses observed. The first book to focus on governing principles rather thanexperimental techniques or specific results, Principles ofAdsorption and Reaction on Solid Surfaces provides students andprofessionals with a quantitative treatment of the application ofprinciples derived from the fields of thermodynamics and reactionrate theory to the investigation of gas adsorption and reaction onsolid surfaces. Writing for a broad-based audience including, amongothers, chemical engineers, chemists, and materials scientists, Dr.Richard I. Masel deftly balances basic background in areas such asstatistical mechanics and kinetics with more advanced applicationsin specialized areas. Principles of Adsorption and Reaction on Solid Surfaces was alsodesigned to provide readers an opportunity to quickly familiarizethemselves with all of the important quantitative surface modelingtechniques now in use. To that end, the author has included all ofthe key equations involved as well as numerous real-worldillustrations and solved examples that help to illustrate how theequations can be applied. He has also provided computer programsalong with universal plots that make it easy for readers to applyresults to their own problems with little computationaleffort. Principles of Adsorption and Reaction on Solid Surfaces is avaluable working resource for chemical engineers, physicalchemists, and materials scientists, and an excellent text forgraduate students in those disciplines.
