Is Hopping A Science?: Selected Topics Of Hopping Conductivity
Author: Issai Shlimak
Publisher: World Scientific
ISBN: 9814663352
Category : Science
Languages : en
Pages : 154
Book Description
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.

Stripes and Related Phenomena
Author: Antonio Bianconi
Publisher: Springer Science & Business Media
ISBN: 0306471000
Category : Technology & Engineering
Languages : en
Pages : 557
Book Description
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.

Theory of Thermoluminescence and Related Phenomena
Author: Reuven Chen
Publisher: World Scientific
ISBN: 9789810222956
Category : Science
Languages : en
Pages : 580
Book Description
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.

Publisher: Newnes
ISBN: 0080932282
Category : Science
Languages : en
Pages : 3572
Book Description
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

Hopping Transport in Solids
Author: M. Pollak
Publisher: Elsevier
ISBN: 0444600817
Category : Science
Languages : en
Pages : 468
Book Description
The hopping process, which differs substantially from conventional transport processes in crystals, is the central process in the transport phenomena discussed in this book. Throughout the book the term ``hopping'' is defined as the inelastic tunneling transfer of an electron between two localized electronic states centered at different locations. Such processes do not occur in conventional electronic transport in solids, since localized states are not compatible with the translational symmetry of crystals.The rapid growth of interest in hopping transport has followed in the footsteps of the development of physics of disordered systems during the last three decades. The intense interest in disordered solids can be attributed to the technological potential of the new noncrystalline materials, as well as to new fundamental problems discovered in solid state physics when a crystal is no longer translationally symmetric.In the last decade hopping systems such as organic polymers, biological materials, many oxide glasses, mesoscopic systems, and the new high-temperature superconducting materials in their normal state have attracted much interest. New phenomena investigated recently include interference and coherent scattering in variable range hopping conduction, mesoscopic effects, relaxation processes and thermo-electric power, and thermal conductivity caused by hopping transport. This volume presents the reader with a thorough overview of these recent developments, written by leading experts in the various fields.

The Morphome Debate
Author: Ana Luís
Publisher: Oxford University Press
ISBN: 0191006645
Category : Language Arts & Disciplines
Languages : en
Pages : 389
Book Description
This volume surveys the current debate on the morphome, bringing together experts from different linguistic fields--morphology, phonology, semantics, typology, historical linguistics--and from different theoretical backgrounds, including both proponents and critics of autonomous morphology. The concept of the morphome is one of the most influential but contentious ideas in contemporary morphology. The term is typically used to denote a pattern of exponence lacking phonological, syntactic, or semantic motivation, and putative examples of morphomicity are frequently put forward as evidence for the existence of a purely morphological level of linguistic representation. Central to the volume is the need to attain a deeper understanding of morphomic patterns, developing stringent diagnostics of their existence, exploring the formal grammatical devices required to characterize them adequately, and assessing their implications for language acquisition and change. The extensive empirical evidence is drawn from a wide range of languages, including Archi, German, Kayardild, Latin and its descendants, Russian, Sanskrit, Selkup, Ulwa, and American Sign Language. As the first book to examine morphomic patterns from such a diverse range of perspectives and on such a broad cross-linguistic basis, The Morphome Debate will be of interest to researchers of all theoretical persuasions in morphology and related linguistic disciplines.
