Book Synopsis Stripes and Related Phenomena by : Antonio Bianconi
Download or read book Stripes and Related Phenomena written by Antonio Bianconi and published by Springer Science & Business Media. This book was released on 2006-04-10 with total page 557 pages. Available in PDF, EPUB and Kindle. Book excerpt: The problem of superconductors has been a central issue in Solid State Physics since 1987. After the discovery of superconductivity (HTSC) in doped perovskites, it was realized that the HTSC appears in an unknown complex electronic phase of c- densed matter. In the early years, all theories of HTSC were focused on the physics of a homogeneous 2D metal with large electron–electron correlations or on a 2D polaron gas. Only after 1990, a novel paradigm started to grow where this 2D metallic phase is described as an inhomogeneous metal. This was the outcome of several experimental evidences of phase separation at low doping. Since 1992, a series of conferences on phase separation were organized to allow scientists to get together to discuss the phase separation and related issues. Following the discovery by the Rome group in 1992 that “the charges move freely mainly in one direction like the water running in the grooves in the corrugated iron foil,” a new scenario to understand superconductivity in the superconductors was open. Because the charges move like rivers, the physics of these materials shifts toward the physics of novel mesoscopic heterostructures and complex electronic solids. Therefore, understanding the striped phases in the perovskites not only provides an opportunity to understand the anomalous metallic state of cuprate superconductors, but also suggests a way to design new materials of technological importance. Indeed, the stripes are becoming a field of general scientific interest.
Book Synopsis Is Hopping A Science?: Selected Topics Of Hopping Conductivity by : Issai Shlimak
Download or read book Is Hopping A Science?: Selected Topics Of Hopping Conductivity written by Issai Shlimak and published by World Scientific. This book was released on 2015-03-16 with total page 154 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book provides an overview of the author's work devoted to experimental study of hopping conductivity, which includes substantial contributions, such as solving the problem of critical indices of the metal-insulator transition in doped semiconductors, investigation of transitions from different kinds of hopping conductivity, development of the 'hopping spectroscopy' method that allows to reveal the details of the density-of-states near the Fermi level — appearance of a hard 'magnetic gap', temperature induced smearing of the soft Coulomb gap, the 'phononless' hopping and so on. A separate chapter is devoted to the hopping photoconductivity and inter-impurity radiative recombination of non-equilibrium carriers. This book is suitable for undergraduate and graduate students in physics, researchers in semiconductor electronics and even for the non-experts who wish to have a notion about hopping mechanism of transport. The explanations in the book are simple and detailed enough to capture the interest of the curious reader.

Book Synopsis Begriffswelt der Feldtheorie by : André Moliton
Download or read book Begriffswelt der Feldtheorie written by André Moliton and published by Springer Science & Business Media. This book was released on 2006 with total page 513 pages. Available in PDF, EPUB and Kindle. Book excerpt: Optoelectronic devices are currently being developed at an extraordinary rate. Organic light-emitting diodes, photovoltaic devices and electro-optical modulators are pivotal to the future of displays, photosensors and solar cells, and communication technologies. This book details the theories underlying the mechanisms involved in the relevant organic materials and covers, at a basic level, how the organic components are made. The first part of the book introduces the fundamental theories used to describe ordered solids and goes onto detail on concepts applicable to localised energy levels. Then the methods used to determine energy levels particular to perfectly ordered molecular and macromolecular systems are discussed along with a detailed consideration of the effects of quasi-particles. The function of excitons and their transfer between two molecules is studied and, in addition, the problems associated with interfaces and charge injection into resistive media are presented. More technological aspects are covered in the second part, which details the actual methods used to fabricate devices based on organic materials, such as dry etching. The principal characterisation techniques are also highlighted. Specific attention is paid to visual displays using organic light-emitting diodes; the conversion of photons into electrical energy (the photovoltaic effect); and for communications and information technologies, the electro-optical modulation of signals.
Book Synopsis Theory of Thermoluminescence and Related Phenomena by : Reuven Chen
Download or read book Theory of Thermoluminescence and Related Phenomena written by Reuven Chen and published by World Scientific. This book was released on 1997 with total page 580 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this book, the authors give an up-to-date account of thermoluminescence (TL) and other thermally stimulated phenomena. Although most recent experimental results of TL in different materials are described in some detail, the main emphasis in the present book is on general processes, and the approach is more theoretical. Thus the details of the possible processes which can take place during the excitation of the sample, and during its heating, are carefully analysed. The methods for analysing TL glow curves are critically discussed, and recommendations as to their application are made. Also discussed is the expected behavior of these phenomena as functions of the experimental parameters, for example, dose of excitation. The consequences of the main applications of TL (for example, radiation dosimetry) are also discussed in detail as are the similarities and dissimilarities of other thermally stimulated phenomena, and the simultaneous measurements of the latter and TL.

Book Synopsis New Horizons in Low-Dimensional Electron Systems by : Hideo Aoki
Download or read book New Horizons in Low-Dimensional Electron Systems written by Hideo Aoki and published by Springer Science & Business Media. This book was released on 1991-12-31 with total page 498 pages. Available in PDF, EPUB and Kindle. Book excerpt: In Bird of Passage by Rudolf Peierls, we find a paragraph in which he de scribes his Cambridge days in the 1930s: On these [relativistic field theory] problems my main contacts were Dirac, and the younger theoreticians. These included in particular Nevill (now Sir Nevill) Mott, perhaps the friendliest among many kind and friendly people we met then. Professor Kamimura became associated with Sir Rudolf Peierls in the 1950s, when he translated, with his colleagues, Peierls's 1955 textbook, Quantum Theory of Solids, into Japanese. This edition, to which Sir Rudolf himself contributed a preface, benefitted early generations of Japanese solid state physicists. Later in 1974/5, during a sabbatical year spent at the Cavendish Laboratory, Professor Kamimura met and began a long association with Sir Nevill Mott. In particular, they developed ideas for disordered systems. One of the outcomes is a paper coauthored by them on ESR-induced variable range hopping in doped semiconductors. A series of works on disordered systems, together with those on two-dimensional systems, have served as building blocks for Physics of Interacting Electrons in Disordered Systems, in the International Series of Monographs on Physics, coauthored by Aoki and published in 1989 by the Oxford University Press. Soon after Professor Kamimura obtained a D. Sc. in 1959 for the work on the ligand field theory under the supervision ofMasao Kotani, his strong con nections in the international physical community began when he worked at the Bell Telephone Laboratories in 1961/64.

Book Synopsis Recovery from Brain Damage by : F.D. Rose
Download or read book Recovery from Brain Damage written by F.D. Rose and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 220 pages. Available in PDF, EPUB and Kindle. Book excerpt: The present volume is based upon the invited review lectures delivered to the European Brain and Behaviour Society's Workshop on Recovery of Function Following Brain Damage held at Goldsmiths' College, University of London, in April 1991. Coming exactly ten years after the Society's ftrst meeting on this subject, held at Erasmus University, Rotterdam, a major objective of the Workshop was to review progress in the intervening years. This task was begun by Professor D. G. Stein in his opening presentation. Looking ahead to possible developments in recovery research in the next decade was the subject of Professor B. Kolb's closing lecture. The intervening presentations reviewed progress made in speciftc areas of recovery research. In addition to reviewing progress over the last decade we sought to achieve an additional objective in the way that the invited review lectures were organised. This was to bring together those doing basic research, usually animal research, and those whose of the lectures were "paired", research interests are more clinically orientated. Thus some one concentrating on the results of animal studies and one on clinical research findings.

Download or read book Comprehensive Semiconductor Science and Technology written by and published by Newnes. This book was released on 2011-01-28 with total page 3572 pages. Available in PDF, EPUB and Kindle. Book excerpt: Semiconductors are at the heart of modern living. Almost everything we do, be it work, travel, communication, or entertainment, all depend on some feature of semiconductor technology. Comprehensive Semiconductor Science and Technology, Six Volume Set captures the breadth of this important field, and presents it in a single source to the large audience who study, make, and exploit semiconductors. Previous attempts at this achievement have been abbreviated, and have omitted important topics. Written and Edited by a truly international team of experts, this work delivers an objective yet cohesive global review of the semiconductor world. The work is divided into three sections. The first section is concerned with the fundamental physics of semiconductors, showing how the electronic features and the lattice dynamics change drastically when systems vary from bulk to a low-dimensional structure and further to a nanometer size. Throughout this section there is an emphasis on the full understanding of the underlying physics. The second section deals largely with the transformation of the conceptual framework of solid state physics into devices and systems which require the growth of extremely high purity, nearly defect-free bulk and epitaxial materials. The last section is devoted to exploitation of the knowledge described in the previous sections to highlight the spectrum of devices we see all around us. Provides a comprehensive global picture of the semiconductor world Each of the work's three sections presents a complete description of one aspect of the whole Written and Edited by a truly international team of experts
Book Synopsis Complexity and Education by : Brent Davis
Download or read book Complexity and Education written by Brent Davis and published by Routledge. This book was released on 2014-06-03 with total page 215 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book explores the contributions, actual and potential, of complexity thinking to educational research and practice. While its focus is on the theoretical premises and the methodology, not specific applications, the aim is pragmatic--to present complexity thinking as an important and appropriate attitude for educators and educational researchers. Part I is concerned with global issues around complexity thinking, as read through an educational lens. Part II cites a diversity of practices and studies that are either explicitly informed by or that might be aligned with complexity research, and offers focused and practiced advice for structuring projects in ways that are consistent with complexity thinking. Complexity thinking offers a powerful alternative to the linear, reductionist approaches to inquiry that have dominated the sciences for hundreds of years and educational research for more than a century. It has captured the attention of many researchers whose studies reach across traditional disciplinary boundaries to investigate phenomena such as: How does the brain work? What is consciousness? What is intelligence? What is the role of emergent technologies in shaping personalities and possibilities? How do social collectives work? What is knowledge? Complexity research posits that a deep similarity among these phenomena is that each points toward some sort of system that learns. The authors’ intent is not to offer a complete account of the relevance of complexity thinking to education, not to prescribe and delimit, but to challenge readers to examine their own assumptions and theoretical commitments--whether anchored by commonsense, classical thought or any of the posts (such as postmodernism, poststructuralism, postcolonialism, postpositivism, postformalism, postepistemology) that mark the edges of current discursive possibility. Complexity and Education is THE introduction to the emerging field of complexity thinking for the education community. It is specifically relevant for educational researchers, graduate students, and inquiry-oriented teacher practitioners.
