Book Synopsis Alkali-doped Fullerides by : Olle Gunnarsson
Download or read book Alkali-doped Fullerides written by Olle Gunnarsson and published by World Scientific. This book was released on 2004 with total page 301 pages. Available in PDF, EPUB and Kindle. Book excerpt: Alkali-doped fullerides have attracted strong interest since their production became possible about fifteen years ago. This book presents recent work which may solve intriguing problems arising from a variety of remarkable properties. For example, these solids are superconductors with high transition temperatures, although the similarity between the electronic and phonon energy scales should suppress superconductivity. Moreover, the Ioffe-Regel condition for electrical conductivity is strongly violated. The book shows why superconductivity is nevertheless possible, owing to a local pairing mechanism. The Ioffe-Regel condition is derived quantum-mechanically, and it is explained why the underlying assumptions are violated for fullerides and high-c cuprates, for example. The book treats electronic and transport properties, reviewing theoretical and experimental results. It focuses on superconductivity, electrical conductivity and metal-insulator transitions, emphasizing the electron-electron and electron-phonon interactions as well as the Jahn-Teller effect.
Book Synopsis Ab Initio Studies on Superconductivity in Alkali-Doped Fullerides by : Yusuke Nomura
Download or read book Ab Initio Studies on Superconductivity in Alkali-Doped Fullerides written by Yusuke Nomura and published by Springer. This book was released on 2016-08-03 with total page 143 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book covers high-transition temperature (Tc) s-wave superconductivity and the neighboring Mott insulating phase in alkali-doped fullerides. The author presents (1) a unified theoretical description of the phase diagram and (2) a nonempirical calculation of Tc. For these purposes, the author employs an extension of the DFT+DMFT (density-functional theory + dynamical mean-field theory). He constructs a realistic electron–phonon-coupled Hamiltonian with a newly formulated downfolding method. The Hamiltonian is analyzed by means of the extended DMFT. A notable aspect of the approach is that it requires only the crystal structure as a priori knowledge. Remarkably, the nonempirical calculation achieves for the first time a quantitative reproduction of the experimental phase diagram including the superconductivity and the Mott phase. The calculated Tc agrees well with the experimental data, with the difference within 10 K. The book provides details of the computational scheme, which can also be applied to other superconductors and other phonon-related topics. The author clearly describes a superconducting mechanism where the Coulomb and electron–phonon interactions show an unusual cooperation in the superconductivity thanks to the Jahn–Teller nature of the phonons.

Book Synopsis Molecular Nanostructures - Proceedings Of The International Winterschool On Electronic Properties Of Novel Materials by : Jorg Fink
Download or read book Molecular Nanostructures - Proceedings Of The International Winterschool On Electronic Properties Of Novel Materials written by Jorg Fink and published by World Scientific. This book was released on 1998-01-15 with total page 570 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume is the latest of the “Kirchberg-Proceedings”. The previous 11 International Winterschools on Electronic Properties of Novel Materials, all held in Kirchberg, Austria, were devoted to conducting polymers, high temperature superconductors, fullerenes, and carbon nanotubes. Fullerenes and nanotubes are still in the center of interest, but the topic of the school and the proceedings is molecular nanostructures in general. The organizers have attempted to treat carbon nanostructures as a special case of molecular nanostructures, which also include silicon clusters, gold clusters, vanadium oxide tubes, and many others. The Winterschool provides a platform for reviewing and discussing new developments in the field of molecular nanostructures and their applications. Materials discussed include fullerenes, fullerene-derived structures, carbonaceous nanotubes, non-carbonaceous nanotubes, layer by layer systems, molecular clusters, new phases of carbon, endohedral compounds and related materials. The book aims to give an overview of the current status of fullerenes, carbon-nanotubes and related molecular nanostructures. The majority of the contributions present the latest results of experiments and calculations conducted in the field. However, about a dozen contain some degree of instructional material which even newcomers will benefit from.
Download or read book The Fullerenes written by H.W. Kroto and published by Newnes. This book was released on 2012-12-02 with total page 327 pages. Available in PDF, EPUB and Kindle. Book excerpt: Until recently, the element carbon was believed to exhibit only two main allotropic forms, diamond and graphite. Research in the US and Europe has now confirmed the existence of a third previously unknown form - buckminsterfullerene (C60) and its relatives, the fullerenes (C24, C28, C32, C70 etc). The story of fullerene chemistry, physics and materials science began in 1985, almost twenty years after the existence of a spherical carbon cluster was first considered. In September 1985 a joint Sussex/Rice Universities team including Kroto, Heath, O'Brien, Curl and Smalley used a powerful mass spectrometric technique to identify the C+60 species, and proposed a spherical structure and the name buckminsterfullerene. It was not, however, until Krätschmer and Huffman reported the isolation of crystals of C60 in 1990 that the closed cage structure of C60 could be confirmed. The Fullerenes documents the work leading up to 1990 and more recent developments in the field of fullerene research and will serve as an indispensible reference tool for all workers in this area.

Available in PDF, EPUB and Kindle. Book excerpt: This is the first of three volumes of the extensively revised and updated second edition of the Handbook of Superconductivity. The past twenty years have seen rapid progress in superconducting materials, which exhibit one of the most remarkable physical states of matter ever to be discovered. Superconductivity brings quantum mechanics to the scale of the everyday world where a single, coherent quantum state may extend over a distance of metres, or even kilometres, depending on the size of a coil or length of superconducting wire. Viable applications of superconductors rely fundamentally on an understanding of this intriguing phenomena and the availability of a range of materials with bespoke properties to meet practical needs. This first volume covers the fundamentals of superconductivity and the various classes of superconducting materials, which sets the context and background for Volumes 2 and 3. Key Features: Covers the depth and breadth of the field Includes contributions from leading academics and industry professionals across the world Provides hands-on guidance to the manufacturing and processing technologies A comprehensive reference, this handbook is suitable for both graduate students and practitioners in experimental physics, materials science and multiple engineering disciplines, including electronic and electrical, chemical, mechanical, metallurgy and others.

Book Synopsis Carbon-based Superconductors by : Junji Haruyama
Download or read book Carbon-based Superconductors written by Junji Haruyama and published by CRC Press. This book was released on 2014-12-16 with total page 316 pages. Available in PDF, EPUB and Kindle. Book excerpt: Superconductors (SCs) are attractive materials in all respects for any community. They provide a deep insight into the physical properties of the condensed matters and also have useful applications as ultra-low-power-dissipation systems that can help resolve the present energy problems. In particular, the recent advancement of carbon-based new superconductors (CNSCs) is significant. Before 2004, the superconducting transition temperature (Tc) of carbon-based SCs was below 1 K, except in fullerene clusters. However, in 2004, a Russian group discovered that diamond highly doped with boron could be an SC at Tc = 4 K. The following year, a group from Cambridge found that calcium-intercalated graphite could be an SC with Tc = 11.5 K. In 2006 and 2008, the editor’s group from Japan also discovered that carbon nanotubes could be SCs at Tc = 12 K. Since then, research on CNSCs has increased notably. A small mass of carbon can produce high phonon frequency and high Debye temperature. Combining these with other specified properties of CNSCs (such as one-dimensional electronic states) is highly expected to open doors to high-Tc superconductivity like those of CuO2- and Fe-based SCs, which were the only SCs to show Tc > 40 K in the past. CNSCs, such as diamond, graphite, carbon nanotubes, fullerenes, and others, are a very attractive field of research, and this book is the first to describe their basic physics and the recent advances toward high Tc in this field.
