Download or read book Relaxation Processes in Molecular Excited States written by J. Fünfschilling and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 282 pages. Available in PDF, EPUB and Kindle. Book excerpt: Relaxation phenomena of excited molecular states are abundant in all nature. They mediate such key processes as photochemical reactions or even the pathways of ordinary chemical reactions. However, for a long time the main research in electronic relaxation processes was concerned with anorganic solids, in part because of their great technological importance (photography, semiconductors ... ) in part also because these compounds were the "workhorses" of the solid state physicists. In the last 30 years, there was a steadily increasing interest in organic molecular systems, first in molecular crystals and later in all forms of molecular solids (glasses, polymers, membranes, ... ). The present volume combines papers on quite different types of relaxation phenomena: the type of solid studied, the electronic states involved, the physical processes responsible for the relaxations are all different. Nevertheless, after reading this book, a more clear and complete picture of the phenomenon "relaxa tion" emerges that proves that this volume is more than just a collection of individual articles. The volume starts with the paper "Spin-lattice and spin-spin relaxation in photo-excited triplet states in molecular crystals" by Jan Schmidt. Even in these seemingly simple systems of isolated guest molecules in a single crystal host, the relaxation phenomena are quite involved and a very thorough investigation is necessary to find the key relaxation processes. The end of the article provides a bridge to the following paper: it treats interactions of two molecules (dimers), where resonant interactions become important and lead to new, characteristic relaxation processes.
Download or read book Optical Absorption of Impurities and Defects in Semiconducting Crystals written by Bernard Pajot and published by Springer Science & Business Media. This book was released on 2010-05-26 with total page 487 pages. Available in PDF, EPUB and Kindle. Book excerpt: Semiconducting and Insulating Crystals details how absorption spectroscopy provides information on the nature, concentration, charge state and configuration of impurities in crystals and also on their kinetics and transformations under annealing. After an introduction of the bulk optical properties of semiconductors and insulators and of impurities in crystals, this book presents the physical bases necessary for the understanding of impurity spectra. The description of various set-ups and accessories used in absorption spectroscopy is followed by a presentation of experimental results on specific impurities and classes of impurities and their relation with those obtained by various computation and by other experimental techniques.
Download or read book Nonlinear Optical Properties of Organic Molecules and Crystals V2 written by D.S. Chemla and published by Elsevier. This book was released on 2012-12-02 with total page 285 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nonlinear Optical Properties of Organic Molecules and Crystals, Volume 2 deals with the nonlinear optical properties of organic molecules and crystals, with emphasis on cubic nonlinear optical effects and and the intermolecular bond. Topics covered include the basic structural and electronic properties of polydiacetylenes; cubic effects in polydiacetylene solutions and films; and degenerate third-order nonlinear optical susceptibility of polydiacetylenes. Dimensionality effects and scaling laws in nonlinear optical susceptibilities are also considered. This volume is comprised of seven chapters divided into two sections and begins with a discussion on the basic structural and electronic properties of polydiacetylenes as well as their methods of preparation. Cubic nonlinearities in polydiacetylene solutions and films are then examined, paying particular attention to polarization in one-dimensional media; multiple reflections of fundamental and harmonic waves; and harmonic generation in an absorbing medium. The following chapters focus on degenerate third-order nonlinear optical susceptibility of polydiacetylenes; dimensionality effects and scaling laws in nonlinear optical susceptibilities; polarizabilities and hyperpolarizabilities of long molecules; and resonant molecular optics. The final chapter analyzes the nonlinear optics of a wide range of compounds that are held together by intermolecular bonding and form supramolecular assemblies. This monograph will be a useful resource for physicists, physical and organic chemists, and those in the field of quantum electronics.

Download or read book Physics of Radiation Effects in Crystals written by R.A. Johnson and published by Elsevier. This book was released on 2012-12-02 with total page 736 pages. Available in PDF, EPUB and Kindle. Book excerpt: ``Physics of Radiation Effects in Crystals'' is presented in two parts. The first part covers the general background and theory of radiation effects in crystals, including the theory describing the generation of crystal lattice defects by radiation, the kinetic approach to the study of the disposition of these defects and the effects of the diffusion of these defects on alloy compositions and phases. Specific problems of current interest are treated in the second part and include anisotropic dimensional changes in x-uranium, zirconium and graphite, acceleration of thermal creep in reactor materials, and radiation damage of semiconductors and superconductors.
Download or read book Solitons written by S.E. Trullinger and published by Elsevier. This book was released on 2012-12-02 with total page 916 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the twenty years since Zabusky and Kruskal coined the term ``soliton'', this concept changed the outlook on certain types of nonlinear phenomena and found its way into all branches of physics. The present volume deals with a great variety of applications of the new concept in condensed-matter physics, which is particularly reached in experimentally observable occurrences. The presentation is not centred around the mathematical aspects; the emphasis is on the physical nature of the nonlinear phenomena occurring in particular situations.With its emphasis on concrete, mostly experimentally verifiable cases, ``Solitons'' constitutes a very readable and instructive introduction to the subject as well as an up-to-date account of current developments in a field of research reaching maturity.

Book excerpt: Introducing the subject of superfluid helium three and polarized liquid helium three, this book is devoted to modern problems in many body physics specific to the quantum fluid helium three. Relationships between properties of helium three and topics in other fields are established including superconductivity, non-linear dynamics, acoustics, and magnetically polarized quantum systems. Among the chapters in this collection one finds valuable reference material and original research not published elsewhere. Advanced research topics are presented in a pedagogical manner, in considerable depth, and with appropriate introductory material sufficiently general to be suitable to the non-specialist.

Available in PDF, EPUB and Kindle. Book excerpt: The transport properties of solids, as well as the many optical phenomena in them are determined by the scattering of current carriers. ``Carrier Scattering in Metals and Semiconductors'' elucidates the state of the art in the research on the scattering mechanisms for current carriers in metals and semiconductors and describes experiments in which these mechanisms are most dramatically manifested.The selection and organization of the material is in a form to prepare the reader to reason independently and to deal just as independently with available theoretical results and experimental data. The subjects dealt with include: - electronic transport theory based on the test-particle and correlation-function concepts; - scattering by phonons, impurities, surfaces, magnons, dislocations, electron-electron scattering and electron temperature; - two-phonon scattering, spin-flip scattering, scattering in degenerate and many-band models.
