Book Description
The theory of surface states underlies our knowledge of the behavior of electrons at solid surfaces, which is of paramount importance in understanding the mechanisms by which solid-state devices operate and catalytic reactions proceed. In this work, the subject is viewed through the "theoretical eye" of a physicist, but the topics are treated in an elementary fashion. The main features of the presentation are its instructive, model-based approach; detailed step-by-step derivations of the equations; smooth progression through the simple wave-function matching techniques to the more sophisticated Green-function methods; and the historical theme, which traces the evolution of the subject from its founding by the Nobel Laureate Igor Tamm in 1932, through the invention of the transistor in 1947 by Schockley, Bardeen and Brattain, to recent developments. The book will appeal to both theoretical and experimental surface scientists from chemistry, materials science, and electronic engineering.

Book Description
In a wide number of economic problems the equilibrium values of the variables can be regarded as solutions of a parametrized constrained maximization problem. This occurs in static as well as dynamic models; in the latter case the choice variables are often paths in certain function spaces and thus can be regarded as points in infinite dimensional spaces. It is sometimes possible to determine qualitative properties of the solutions with respect to changes in the parameters of the model. The study of such properties is often called comparative statics; [15], [2], and [10]. Certain comparative static properties of the maxima have proven to be of particular importance for economic theory, since the works of Slutsky, Hicks, and Samuelson [15]: they have been for- lated in terms of synunetry and negative semidefiniteness of a matrix, called the Slutsky-Hicks-Samuelson matrix. A discussion of this matrix and its applications is given in Section 1. The study of these properties in economic theory, however, has so far been restricted to static models where the choice variable and the parameters are elements in Euclidean spaces, and where there is only one constraint.

Book Description
This volume continues the development of the Modern Aspects series in the electrochemical field. The series is now 18 years old, and it is relevant to note the degree of evolution that electro chemistry has undergone during this time, for it affects the character of the articles chosen. The trend is towards development of inter disciplinary areas of electrochemical science, with full stress upon the many directions of applications of knowledge of electrode processes. The degree of import which should be attached to electro chemical science arises from the changes in technology which must be made during the next few decades. These clearly involve a massive electrification and the gradual elimination of the present fossil fuel economy, for both ecological and economic reasons. Research on the fundamental aspects of the field-slow in development to a standard-must be promulgated, but its justification is the modern provisionofa basis for the needed future electrochemical technology. One vast area of potential application of electrochemical concepts is omitted by the present attitude. It is, of course, the electro biological aspect, perhaps, finally, the largest area of all for fruitful applications. These concepts are reflected in the editors' choice of chapters. Quantum mechanical descriptions of surfaces must be bravely faced. Oscillatory aspects of electrochemical systems are often met in nature and demand attention at a fundamental level. Organic electrochemistry is in an ascending phase. With the electro biological v Preface vi article, we hope to stimulate a beginning of electrodic applications in this area.

Book Description
This book is the second volume in the Handbook of Surface Science series and deals with aspects of the electronic structure of surfaces as investigated by means of the experimental and theoretical methods of physics. The importance of understanding surface phenomena stems from the fact that for many physical and chemical phenomena, the surface plays a key role: in electronic, magnetic, and optical devices, in heterogenous catalysis, in epitaxial growth, and the application of protective coatings, for example. Therefore a better understanding and, ultimately, a predictive description of surface and interface properties is vital for the progress of modern technology. An investigation of surface electronic structure is also central to our understanding of all aspects of surfaces from a fundamental point of view. The chapters presented here review the goals achieved in the field and map out the challenges ahead, both in experiment and theory.

Book Description
As was announced two years ago, the description of the physical properties of molybde num has now been completed in the present volume up to page 124. Whereas most properties, e.g., the electrical, magnetic, and optical properties, are dealt with in the usual manner, the results of studies of the atom and ion emission had to be presented in a revised form, comprising not only the most recent data but having in mind also the corresponding data for tungsten, which will be represented in a supplement volume now in preparation. The various modes of electron emission have also been studied in great detail. Many more pages (exactly 226 pages, as contrasted to three pages in the Main Volume) were needed to present the electrochemical data for molybdenum, which were published to an astonishingly great extent by Russian workers. The large volume of literature is due to the extensive industrial application of the metaL, cf. "MoLybdän" Erg.-Bd. A 1, 1977, and to its occurrence in various oxidation states. Thus the equilibrium between an Mo eLectrode and Mo ions or between an inert eLectrode and Mo ions is deaLt with in the chapters "Standard PotentiaLs" and "PotentiaLs", whereas kinetics and reaction mechanisms of the reduction and oxidation of Mo ions on a dropping mercury electrode and other inert eLectrodes can be found in the chapter "Polarography/ Voltammetry."
