Book Description
In this new work, the focus is on the dynamical response of metal electrons to several types of incident electromagnetic fields. The author, an eminent theorist, discusses Time-Dependent Local Density Approximation's importance in both elucidating electronic surface excitations and describing the ground state properties of electronic systems. Chapters detail theoretical formulations and computational procedures, covering such areas as single-particle and collective modes, spatial distribution of the induced surface charges, and local electric fields. Excitation spectra are shown for a variety of clean simple metals, noble metals, chemisorbed overlayers, charged surfaces, and small metal particles.

Book Description
Understanding energy dissipation mechanisms is a field of present-day scientific interest. Experimental results for electronic excitations in metals propose a measurable electronic excitation during many processes involving a metal surface, including epitaxy. While the role of the nuclear excitation processes is comparatively well understood, the role of electronic excitation processes in the energy dissipation during adsorption and other dynamical processes at surfaces is elusive. One of the reasons is that the interaction dynamics is often treated on a Born- Oppenheimer potential energy surface, which is, strictly speaking, not justified for metals, but lifting this restriction is computationally demanding. The focus of this book is the investigation of a perturbative approach to calculate electronic excitations. After a basic introduction into some major aspects of Density Functional Theory calculations, a time-dependent perturbative approach to calculate electronic excitations is developed. This approach is then applied to several model systems, and the results are compared to available experimental data, and other theoretical approaches.

Book Description
Progress continues in the theoretical treatment of surfaces and processes on surfaces based on first-principles methods, i.e. without invoking any empirical parameters. In this book, the theoretical concepts and computational tools necessary and relevant for a microscopic approach to the theoretical description of surface science is presented, together with a detailed discussion of surface phenomena. This makes the book suitable for both graduate students and for experimentalists seeking an overview of the theoretical concepts in surface science. This second enlarged edition has been carefully revised and updated, a new chapter on surface magnetism is included, and novel developments in theoretical surface science are addressed.

Book Description
This volume is devoted principally to optical spectroscopies of material surfaces and also encompasses scattering techniques and theoretical response analysis as well as spectroscopies. In addition to solid surfaces some attention is also devoted to interfaces between two solids, between a solid and a liquid and to a liquid-vapor interface. These surfaces may be clean and perfect, in which case the purpose of the spectroscopical method at hand is to determine the deviation of the atomic structure in the surface region from that in the bulk, namely the surface reconstruction. Otherwise the surface may be imperfect due to roughness, strain or overlayers, in which case the spectroscopy can yield information on the nature of such imperfections, including the monitoring of growth processes. One of the foremost purposes of surface spectroscopies is to extract information on atomic and molecular adsorbates on solid surfaces. Most of the 10 chapters are concerned with photonic sources of excitation, the respective spectral regions ranging from the far infrared to X-rays. In conclusion this book provides a state-of-the-art review of all major types of photonic probes of surfaces and interfaces and deals with both applications and experiment and theory.

Book Description
Electronic excitation is a means to change materials properties. This book analyses the important features of the changes induced by electronic excitation, identifies what is critical, and provides a basis from which materials modification can be developed successfully. Electronic excitation by lasers or electron beams can change the properties of materials. In the last few years, there has been a mix of basic science, of new laser and electron beam tools, and of new needs from microelectronics, photonics and nanotechnology. This book extends and synthesises the science, addressing ideas like energy localisation and charge localisation, with detailed comparisons of experiment and theory. It also identifies the ways this understanding links to technological needs, like selective removal of material, controlled changes, altering the balance between process steps, and possibilities of quantum control. This book will be of particular interest to research workers in physics, chemistry, electronic engineering and materials science.

Book Description
Using lasers to induce and probe surface processes has the advantages of quantum state specificity, species selectivity, surface sensitivity, fast time-resolution, high frequency resolution, and accessibility to full pressure ranges. These advantages make it highly desirable to use light to induce, control, or monitor surface chemical and physical processes. Recent applications of laser based techniques in studying surface processes have stimulated new developments and enabled the understanding of fundamental problems in energy transfer and reactions. This volume will include discussions on spectroscopic techniques, energy transfer, desorption dynamics, and photochemistry.
