Описание: This book provides an easily understandable introduction to solid state physics for chemists and engineers. Band theory is introduced as an extension of molecular orbital theory, and its application to organic materials is described. Phenomena beyond band theory are treated in relation to magnetism and electron correlation, which are explained in terms of the valence bond theory and the Coulomb and exchange integrals. After the fundamental concepts of magnetism are outlined, the relation of correlation and superconductivity is described without assuming a knowledge of advanced physics. Molecular design of organic conductors and semiconductors is discussed from the standpoint of oxidation-reduction potentials, and after a brief survey of organic superconductors, various applications of organic semiconductor devices are described. This book will be useful not only for researchers but also for graduate students as a valuable reference.

Описание: Historically, quasi-low-dimensional superconductors were considered as the main candidates to observe high-temperature superconductivity. For a disc- sion of the related exotic mechanisms of superconductivity, suggested by W.A. Little and V.L. Ginzburg, see a chapter by D. J erome in this volume. Unf- tunately, high-temperature superconductivity has not been discovered yet in quasi-one-dimensional (Q1D) and quasi-two-dimensional (Q2D) organic ma- rials. Nevertheless, very rich and, in many cases, unique physical properties of their metallic, superconducting, charge- and spin-density-wave phases allowed P.M. Chaikin to claim that the ?rst organic superconductors, (TMTSF) X, 2 are probably the most interesting electronic materials ever discovered. Our book welcomes a reader to a fascinating world of exotic condensed matter physics, low temperatures, and high and ultrahigh magnetic ?elds. It is written by leading experts in the area from USA, France, Japan, Russia, United Kingdom, Germany, Canada, South Korea, Croatia, Hungary, and Switzerland. The book consists of six parts, subdivided into 27 chapters, which contain both the experimental results and their theoretical explanations. The majority of the chapters contain pedagogical introductions and all necessary illustrations to be read separately. Although we concentrate on physical p- nomena, in the most chapters related chemistry and structural aspects of Q1D and Q2D organic materials are also discussed."
Описание: It focuses on quasi-two-dimensional organic conductors of the ГЋВё-(BEDT-TTF)2X family, which form anisotropic triangular lattices, and examines their electronic properties using various measurements: resistivity, time-resolved electric transport, X-ray diffraction analysis, and nuclear magnetic resonance spectroscopy.

Описание: The discovery of high temperature superconductors (HTS) in 1986 by two IBM scientists led to an unprecedented explosion of research and development efforts world-wide because of the significant potential for practical applications offered by these materials. However, the early euphoria created by the exciting prospects was dampened by the daunting task of fabricating these materials into useful forms with acceptable superconducting properties. Progress towards this goal has been hindered by many intrinsic materials problems, such as weak-links, flux-creep, and poor mechanical properties.The above problems led to the development of the Second-Generation of HTS wires. Three methods were invented to produce flexible metallic substrates, which were also crystallographically biaxially textured, and resembled a long, mosaic single crystal. The first method invented is the Ion-Beam-Assisted-Deposition (IBAD). The second method developed was the Inclined-Substrate-Deposition (ISD). The third method invented is called the Rolling-assisted-biaxially-textured-substrates (RABiTS).The book is divided into four sections. The first section discusses the three methods to fabricate biaxially textured substrates, upon which, epitaxial YBCO or other HTS materials can be deposited to realize a single-crystal-like HTS wire. The second section includes chapters on various methods of HTS deposition such as pulsed laser ablation (PLD), thermal co-evaporation, sputtering, pulsed electron beam deposition, ex-situ BaF2 by co-evaporation flowed by annealing, chemical solution based ex-situ processes, jet vapor deposition, metal organic chemical vapor deposition (MOCVD), and liquid phase epitaxy (LPE). The third section includes detailed chapters on other HTS materials such as the various Tl-based and Hg-based conductors. These Second-Generation HTS conductors, also referred to as "Coated conductors" represent one of the most exciting developments in HTS technology. HTS wires based on this technology have the potential to carry 100-1000 times the current without resistance losses of comparable copper wire. HTS power equipment based on these HTS conductors has a potential to be half the size of conventional alternatives with the same or higher power rating and less than one half the energy losses. Upgrading of the world-wide electric power transmission and distribution with HTS based devices can significantly help in meeting the growing demand for electricity world-wide. There is little question that superconducting technology based on the Next-Generation HTS Superconducting Wires will make a substantial impact on the way we generate, transmit, distribute and use electric power. Of course the question is - how soon?
Описание: Advances in the physics and chemistry of low-dimensional systems have been really magnificent in the last few decades. Examples of quasi-two-dimensional systems are high temperature su- perconductors (HTSC) based on copper oxides LA2CU04, YBa2Cu306+y and organic superconductors based on BEDT -TIP molecules.

Описание:
This Special Issue of Crystals contains papers focusing on various properties of conducting ceramics. Multiple aspects of both the research and application of this group of materials have been addressed. Conducting ceramics are the wide group of mostly oxide materials which play crucial roles in various technical applications, especially in the context of the harvesting and storage of energy. Without ion-conducting oxides, such as yttria-stabilized zirconia, doped ceria devices such as solid oxide fuel cells would not exist, not to mention the wide group of other ion conductors which can be applied in batteries or even electrolyzers, besides fuel cells. The works published in this Special Issue tackle experimental results as well as general theoretical trends in the field of ceramic conductors, or electroceramics, as it is often referred to.

Описание:
The success of spintronics -- the science and technology of storing, processing, sensing and communicating information using the quantum mechanical spin degree of freedom of an electron -- is critically dependent on the ability to inject, detect and manipulate spins in semiconductors either by incorporating ferromagnetic materials into device architectures or by using external magnetic and electric fields. In spintronics, the controlled generation and manipulation of spin polarization in nonmagnetic semiconductors is required for the design of spin-sensitive devices ranging from spin-qubit hosts, quantum memory and gates, quantum teleporters, spin polarizers and filters, spin-field-effect-transistors, and spin-splitters, among others. One of the major challenges of spintronics is to control the creation, manipulation, and detection of spin polarized currents by purely electrical means. Another challenge is to preserve spin coherence in a device for the longest time or over the longest distance in order to produce reliable spintronic processors. These challenges remain daunting, but some progress has been made recently in overcoming some of the steepest obstacles. This book covers some of the recent advances in the field of spintronics using semiconductors.
