Book Description
This book summarizes the current status of theoretical and experimental progress in 2 dimensional graphene-like monolayers and few-layers of transition metal dichalcogenides (TMDCs). Semiconducting monolayer TMDCs, due to the presence of a direct gap, significantly extend the potential of low-dimensional nanomaterials for applications in nanoelectronics and nano-optoelectronics as well as flexible nano-electronics with unprecedented possibilities to control the gap by external stimuli. Strong quantum confinement results in extremely high exciton binding energies which forms an interesting platform for both fundamental studies and device applications. Breaking of spatial inversion symmetry in monolayers results in strong spin-valley coupling potentially leading to their use in valleytronics. Starting with the basic chemistry of transition metals, the reader is introduced to the rich field of transition metal dichalcogenides. After a chapter on three dimensional crystals and a description of top-down and bottom-up fabrication methods of few-layer and single layer structures, the fascinating world of two-dimensional TMDCs structures is presented with their unique atomic, electronic, and magnetic properties. The book covers in detail particular features associated with decreased dimensionality such as stability and phase-transitions in monolayers, the appearance of a direct gap, large binding energy of 2D excitons and trions and their dynamics, Raman scattering associated with decreased dimensionality, extraordinarily strong light-matter interaction, layer-dependent photoluminescence properties, new physics associated with the destruction of the spatial inversion symmetry of the bulk phase, spin-orbit and spin-valley couplings. The book concludes with chapters on engineered heterostructures and device applications such as a monolayer MoS2 transistor. Considering the explosive interest in physics and applications of two-dimensional materials, this book is a valuable source of information for material scientists and engineers working in the field as well as for the graduate students majoring in materials science.

Chemical Mössbauer Spectroscopy

ISBN: 1461324319
Category : Science
Languages : en
Pages : 381
Book Description
The past twenty five years - roughly the period from 1960 to 1985 - have been by all measures among the most exciting and challenging times of our science. The increasing sensitivity of chemical instrumentation, the introduction of the routine use of computers for data reduction and of microprocessors for instrumental control, the wide-spread utilization of lasers, and the disappearance of traditional disciplinary boundaries between scientific fields are but a few of the examples one could cite to support the introductory contention. Almost all of these developments have had their impact on the development of Mossbauer Effect Spectroscopy into a technique par excellence for the elucidation of problems in all areas of chemistry and its associated sister sciences. Indeed, because this spectroscopy is based on fundamental phenomena in nuclear physics, is described in terms of the theory of the solid state and structural chemistry, is useful in the understanding of chemical reactivity and biological phenomena, and can serve to supplement information developed by many other experimental techniques, it has provided an unparalleled opportunity for the exchange of ideas among practitioners of a very wide variety of subfields of the physical and biological sciences. The present collection of contributions is the direct result of such an interaction.

Topological Geometrodynamics
Author: Matti Pitkanen
Publisher: Bentham Science Publishers
ISBN: 1681081792
Category : Science
Languages : en
Pages : 1235
Book Description
Topological geometrodynamics (TGD) is a modification of the theory of general relativity inspired by the problems related to the definition of inertial and gravitational energies in the earlier hypotheses. TGD is also a generalization of super string models. TGD brings forth an elegant theoretical projection of reality and builds upon the work by renowned scientists (Wheeler, Feynman, Penrose, Einstein, Josephson to name a few). In TGD, Physical space-time planes are visualized as four-dimensional surfaces in a certain 8-dimensional space (H). The choice of H is fixed by symmetries of standard model and leads to a geometric mapping of known classical fields and elementary particle numbers. TGD differs from Einstein’s geometrodynamics in the way space-time planes or ‘sheets’ are lumped together. Extending the theory based on fusing number concepts implies a further generalisation of the space-time concept allowing the identification of space-time correlates of cognition and intentionality. Additionally, zero energy ontology forces an extension of quantum measurement theory to a theory of consciousness and a hierarchy of phases is identified. Dark matter is thus predicted with far reaching implications for the understanding of consciousness and living systems. Therefore, it sets a solid foundation for modeling our universe in geometric terms. Topological Geometrodynamics: An Overview explains basic and advanced concepts about TGD. The book covers introductory information and classical TGD concepts before delving into twistor-space theory, particle physics, infinite-dimensional spinor geometry, generalized number theory, Planck constants, and the applications of TGD theory in research. The book is a valuable guide to TDG theory for researchers and advanced graduates in theoretical physics and cosmology.

Strongly Coupled Coulomb Systems
Author: Gabor J. Kalman
Publisher: Springer Science & Business Media
ISBN: 0306470861
Category : Science
Languages : en
Pages : 699
Book Description
The International Conference on Strongly Coupled Coulomb Systems was held on the campus of Boston College in Newton, Massachusetts, August 3–10, 1997. Although this conference was the first under a new name, it was the continuation of a series of international meetings on strongly coupled plasmas and other Coulomb systems that started with the NATO Summer Institute on Strongly Coupled Plasmas, almost exactly twenty years prior to this conference, in July of 1977 in Orleans la Source, France. Over the intervening period the field of strongly coupled plasmas has developed vigorously. In the 1977 meeting the emphasis was on computer (Monte Carlo and molecular dynamics) simulations which provided, for the first time, insight into the rich and new physics of strongly coupled fully ionizedplasmas. While theorists scrambled to provide a theoretical underpinning for these results, there was also a dearth of real experimental input to reinforce the computer simulations. Over the past few years this situation has changed drastically and a variety of direct experiments on classical, pure, strongly correlated plasma systems (charged particle traps, dusty plasmas, electrons on the surface of liquid helium, etc. ) have become available. Even more importantly, entire new area of experimental interest in condensed matter physics have opened up through developments in nano-technology and the fabrication of low-dimensional systems, where the physical behavior, in many ways, is similar to that in classical plasmas. Strongly coupled plasma physics has always been an interdisciplinaryactivity.

Principles of Mössbauer Spectroscopy
Author: T. C. Gibb
Publisher: Springer
ISBN: 148993023X
Category : Technology & Engineering
Languages : en
Pages : 262
Book Description
The emergence of M6ssbauer spectroscopy as an important experi mental technique for the study of solids has resulted in a wide range of applications in chemistry, physics, metallurgy and biophysics. This book is intended to summarize the elementary principles of the technique at a level appropriate to the advanced student or experienced chemist requiring a moderately comprehensive but basically non-mathematical introduction. Thus the major part of the book is concerned with the practical applications of Mossbauer spectroscopy, using carefully selected examples to illustrate the concepts. The references cited and the bibliography are intended to provide a bridge to the main literature for those who subseouent ly require a deeper knowledge. The text is complementary to the longer research monograph, 'Mossbauer Spectroscopy', which was written a few years ago in co-authorship with Professor N.N. Greenwood, and to whom I am deeply indebted for reading the preliminary draft of the present volume. I also wish to thank my many colleagues over the past ten years, and in particular Dr. R. Greatrex, for the many stimu lating discussions which we have had together. However my greatest debt is to my wife, who not only had to tolerate my eccen tricities during the gestation period, but being a chemist herself was also able to provide much useful criticism of the penultirna te draft.
