Book Description
This book introduces readers to the physics governing electron emission under high voltages and temperatures, and highlights recent modeling and numerical developments for describing these phenomena. It begins with a brief introduction, presenting several applications that have driven electron emission research in the last few decades. The authors summarize the most relevant theories including the physics of thermo-field electron emission and the main characteristic parameters. Based on these theories, they subsequently describe numerical multi-physics models and discuss the main findings on the effect of space charges, emitter geometry, pulse duration, etc. Beyond the well-known photoelectric effect, the book reviews recent advanced theories on photon-metal interaction. Distinct phenomena occur when picosecond and femtosecond lasers are used to irradiate a surface. Their consequences on metal electron dynamics and heating are presented and discussed, leading to various emission regimes – in and out of equilibrium. In closing, the book reviews the effects of electron emission on high-voltage operation in vacuum, especially breakdown and conditioning, as the most common examples. The book offers a uniquely valuable resource for graduate and PhD students whose work involves electron emission, high-voltage holding, laser irradiation of surfaces, vacuum or discharge breakdown, but also for academic researchers and professionals in the field of accelerators and solid state physics with an interest in this highly topical area.

Book Description
Thermionic Phenomena is the third volume of the series entitled The Collected Works of Irving Langmuir. This volume compiles articles written during the 1920's and early 1930's, the period when the science of thermionics is beginning to be of importance. This text is divided into two parts. The first part discusses vacuum pumps, specifically examining the effect of space charge and residual gases on thermionic currents in high vacuum. This part also explains fundamental phenomena in electron tubes having tungsten cathodes and the use of high-power vacuum tubes. The second part of this text looks into the electron emission and adsorbed films, specifically studying the relation between contact potentials and electrochemical action and other related topics on electron emission. This publication will be invaluable to those interested in the works of Langmuir, particularly on thermionic phenomena.

Book Description
It is widely recognized that an understanding of the physical and chemical properties of clusters will give a great deal of important information relevant to surface and bulk properties of condensed matter. This relevance of clusters for condensed matter is one of the major motivations for the study of atomic and molecular clusters. The changes of properties with cluster size, from small clusters containing only a few atoms to large clusters containing tens of thousands of atoms, provides a unique way to understand and to control the development of bulk properties as separated units are brought together to form an extended system. Another important use of clusters is as theoretical models of surfaces and bulk materials. The electronic wavefunctions for these cluster models have special advantages for understanding, in particular, the local properties of condensed matter. The cluster wavefunctions, obtained with molecular orbital theory, make it possible to relate chemical concepts developed to describe chemical bonds in molecules to the very closely related chemical bonding at the surface and in the bulk of condensed matter. The applications of clusters to phenomena in condensed matter is a cross-disciplinary activity which requires the interaction and collaboration of researchers in traditionally separate areas. For example, it is necessary to bring together workers whose background and expertise is molecular chemistry with those whose background is solid state physics. It is also necessary to bring together experimentalists and theoreticians.

Book Description
This book is devoted to a thorough investigation of the physics and applications of the vacuum arc – a highly-ionized metallic plasma source used in a number of applications – with emphasis on cathode spot phenomena and plasma formation. The goal is to understand the origins and behavior of the various complex and sometimes mysterious phenomena involved in arc formation, such as cathode spots, electrode vaporization, and near-electrode plasma formation. The book takes the reader from a model of dense cathode plasma based on charge-exchange ion-atom collisions through a kinetic approach to cathode vaporization and on to metal thermophysical properties of cathodes. This picture is further enhanced by an in-depth study of cathode jets and plasma acceleration, the effects of magnetic fields on cathode spot behavior, and electrical characteristics of arcs and cathode spot dynamics. The book also describes applications to space propulsion, thin film deposition, laser plasma generation, and magnetohydrodynamics, making this comprehensive and up-to-date volume a valuable resource for researchers in academia and industry.
