Photoemission Studies of High-Temperature Superconductors by David W. Lynch,Clifford G. Olson Pdf

This book describes the current status and results of photoelectron spectroscopic techniques, both theoretical and experimental, that have been applied to the study of the cuprate ("high-temperature") superconductors. The techniques described include angle-resolved photoelectron spectroscopy of valence electrons, core level spectra (XPS), and some special variations, such as resonance photoemission. Attention is paid to the difficulties in interpreting such spectra and to the problems obtaining good sample surfaces and high resolution, comparing results from other experimental techniques as well. The authors also outline expected future developments in the techniques. This book will be of great interest to graduate students and researchers in physics, chemistry and materials science with an interest in high temperature superconductors.

Angle-Resolved Photoemission Spectroscopy on High-Temperature Superconductors by Junfeng He Pdf

This book mainly focuses on the study of the high-temperature superconductor Bi2Sr2CaCu2O8+δ (Bi2212) and single-layer FeSe film grown on SrTiO3 (STO) substrate by means of angle-resolved photoemission spectroscopy (ARPES). It provides the first electronic evidence for the origin of the anomalous high-temperature superconductivity in single-layer FeSe grown on SrTiO3 substrate. Two coexisted sharp-mode couplings have been identified in superconducting Bi2212. The first ARPES study on single-layer FeSe/STO films has provided key insights into the electronic origin of superconductivity in this system. A phase diagram and electronic indication of high Tc and insulator to superconductor crossover have been established in the single-layer FeSe/STO films. Readers will find essential information on the techniques used and interesting physical phenomena observed by ARPES.

Photoemission Spectroscopy on High Temperature Superconductor by Wentao Zhang Pdf

This book mainly focuses on the study of the high-temperature superconductor Bi2Sr2CaCu2O8 by vacuum, ultra-violet, laser-based, angle-resolved photoemission spectroscopy (ARPES). A new form of electron coupling has been identified in Bi2212, which occurs in the superconducting state. For the first time, the Bogoliubov quasiparticle dispersion with a clear band back-bending has been observed with two peaks in the momentum distribution curve in the superconducting state at a low temperature. Readers will find useful information about the technique of angle-resolved photoemission and the study of high-temperature superconductors using this technique. Dr. Wentao Zhang received his PhD from the Institute of Physics at the Chinese Academy of Sciences.

Physics and Materials Science of High Temperature Superconductors, II by R. Kossowsky,Bernard Raveau,Dieter Wohlleben,Stamatis K. Patapis Pdf

Physics and Materials Science of High Temperature Superconductors, II represents the results of a fruitful dialogue between physicists and materials scientists which took place under the auspices of a NATO Advanced Study Institute in Porto Carras, Greece, between 18 and 31 August, 1991. It builds on and carries forward the success of NATO ASI 181 published in 1990. The theoretical side of the discussions reveal the basic premise of the phenomenological and Ginzburg-Landau theories of superconductivity, the implications of short coherence length, long penetration depth, the melting of flux lattices, and other matters, while the materials science includes discussions of microstructures, local inhomogeneities, deviations from ideal chemistry, the effects of systematic errors in materials preparation, the definition of imperfections, and the utilization of common materials analysis techniques. The reader will be made aware of the potential significance of Angstrom scale structural and chemical details, and the need to consider basic theoretical concepts when designing procedures to process viable, solid conductors, specifically the effects of oxygen stoichiometry and deviations from it, as well as the microstructural demands on pinning in the light of very short coherence lengths.

New Topics in Superconductivity Research by Barry P. Martins Pdf

Superconductivity is the ability of certain materials to conduct electrical current with no resistance and extremely low losses. High temperature superconductors, such as La2-xSrxCuOx (Tc=40K) and YBa2Cu3O7-x (Tc=90K), were discovered in 1987 and have been actively studied since. In spite of an intense, world-wide, research effort during this time, a complete understanding of the copper oxide (cuprate) materials is still lacking. Many fundamental questions are unanswered, particularly the mechanism by which high-Tc superconductivity occurs. More broadly, the cuprates are in a class of solids with strong electron-electron interactions. An understanding of such "strongly correlated" solids is perhaps the major unsolved problem of condensed matter physics with over ten thousand researchers working on this topic. High-Tc superconductors also have significant potential for applications in technologies ranging from electric power generation and transmission to digital electronics. This ability to carry large amounts of current can be applied to electric power devices such as motors and generators, and to electricity transmission in power lines. For example, superconductors can carry as much as 100 times the amount of electricity of ordinary copper or aluminium wires of the same size. Many universities, research institutes and companies are working to develop high-Tc superconductivity applications and considerable progress has been made. This volume brings together new leading-edge research in the field.

High Temperature Superconductivity by D.P Tunstall,D.W Barford Pdf

High Temperature Superconductivity provides a broad survey of high temperature superconductivity, discussing the adaptations of experimental and theoretical techniques and methods that take advantage of the revolutionary properties of high temperature superconductors. Distinguished engineers, chemists, and experimental and theoretical physicists introduce their own particular area of the field before going on to explain current theories and techniques. The book is divided into three sections: materials, mechanisms, and devices. Topics covered include synthetic approaches to the growth of new materials; optical, magnetic, and electrical characterization of synthesized materials; strong correlations; the magnon pairing mechanism; and technical background of device performance in new materials. A coherent introduction to high temperature superconductivity, this volume will be invaluable to researchers in condensed matter physics, chemistry, materials science, and engineering.

High-Temperature Superconductivity by J. Ashkenazi,S.E. Barnes,F. Zuo,G.C. Vezzoli,B.M. Klein Pdf

This volume contains the proceedings of the University of Miami Workshop on the subject of "Electronic Structure and Mechanisms for High Temperature Super conductivity". The workshop was held at the James L. Knight Physics Building on the campus of the University of Miami, Coral Gables, 3-9 January 1991. Some 106 scientists from 12 countries attended this workshop, most of whom presented either invited or contributed papers. The reader will find in this volume a series of papers discussing the most im portant experimental and theoretical developments as of winter/spring 1990/1991. Despite more than four years of intensive research on high-T materials, there has c been considerable controversy both with respect to the interpretation of experiment and even more so in connection with the construction of an appropriate theory. In this regard, workshops such as this, gathering scientists with many viewpoints, and varying specialization, and fostering constructive discussions, are important in the de velopment of a common ground. Of major concern in the present context were the basic physical processes involved in high-temperature superconductivity.
