Book excerpt: 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.

This book was released on 2022-09-13 with total page 113 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis makes significant advances towards an understanding of superconductivity in the cuprate family of unconventional, high-temperature superconductors. Even though the high-temperature superconductors were discovered over 35 years ago, there is not yet a general consensus on an acceptable theory of superconductivity in these materials. One of the early proposals suggested that collective magnetic excitations of the conduction electrons could lead them to form pairs, which in turn condense to form the superconducting state at a critical temperature Tc. Quantitative calculations of Tc using experimental data were, however, not available to verify the applicability of this magnetic mechanism. In this thesis, the author constructed an angle-resolved photoemission apparatus that could provide sufficiently accurate data of the electronic excitation spectra of samples in the normal state, data which was furthermore unusually devoid of any surface contamination. The author also applied the Bethe-Salpeter method to his uncommonly pristine and precise normal state data, and was able to predict the approximate superconducting transition temperatures of different samples. This rare combination of experiment with sophisticated theoretical calculations leads to the conclusion that antiferromagnetic correlations are a viable candidate for the pairing interaction in the cuprate superconductors.

This book was released on 2012-12-02 with total page 590 pages. Available in PDF, EPUB and Kindle. Book excerpt: These volumes contain 365 of the 505 papers presented at the VUV-11 Conference, held at Rikkyo University, Tokyo, from August 27th to September 1st 1995. The papers are divided into three sections: atomic and molecular spectroscopy, solid state spectroscopy and instrumentation and technological applications. New aspects presented were both quantitative and qualitative improvements in fluorescence spectroscopy and magnetic circular dichroism measurements. The fluorescence data are complementary to those of photoemission in a sense but they appear to open up a new method to analyze the optical excitation and relaxation processes. The application of magnetic circular dichroism has proved to be useful not only in analyzing the electronic structures of magnetic materials but also in practical applications to material engineering as found in experiments combined with photoelectron microscopy. Excellent developments in applications are only found in the field of surface photochemistry, where the technique of etching using VUV light has been appreciably refined. Although the majority of distinctive scientific features in the VUV-11 Conference have been brought about by the application of synchrotron radiation, experiments using a different type of light source appear to have progressed steadily. This is evident in the studies of plasma radiation.

Download or read book Angle Resolved Photoemission written by S.D. Kevan and published by Elsevier. This book was released on 1992-05-15 with total page 627 pages. Available in PDF, EPUB and Kindle. Book excerpt: Angle-resolved photoemission has become an indispensable tool for solid state and surface physicists and chemists. This book covers the underlying phenomenology of the technique, reviews its application to existing problems, and discusses future applications. The book is particularly timely given the significant improvements in experimental and theoretical methodology which have recently been or soon will be attained, namely, ultrahigh resolution studies using improved sources of synchrotron radiation, quasiparticle interpretation of measured dispersion relations and spectra, in situ growth of novel materials, etc. The technique has been applied predominantly to understand materials for which the one-electron paradigm is a reasonable approximation. Most chapters discuss this type of experiment: 2D and 3D states in metals and semiconductors, extrinsic states induced by adsorption, etc. Applications of the technique to materials where electron correlation plays a comparable role to that of solid state hybridization, ferro- and antiferromagnets, high Tc superconductors, etc. are rapidly growing in popularity. These areas are also discussed and a foundation is laid for further experiments in this direction. Almost all chapters contain comprehensive bibliographies and compendia of systems studied. The book has an extensive index which cross references applications and systems studied.

This book was released on 2013-03-09 with total page 1070 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since the First International Symposium on Superconductivity (ISS '88) was held in Nagoya, Japan in 1988, significant advances have been achieved in a wide range of high temperature superconductivity research. Although the T c's of recently discovered oxide superconductors still do not exceed the record high value of 125K reported before that meeting, the enrichment in the variety of materials should prove useful to the investigation of the fundamental mechanism of superconductiv ity in these exotic materials. The discovery of the n-type superconducting oxides proved to oppose the previously held empirical fact that the charge carriers in all oxide superconductors were holes. In addition, optimization of the charge carrier density has been established as a technique to improve the superconducting proper ties of the previously known oxide materials. Many new experimental and theoreti cal advances have been made in understanding both the fundamental and the applied aspects of high temperature superconductivity. In this latter area, various new processing techniques have been investigated, and the critical current densities and other significant parameters of both bulk and thin film oxide superconductors are rapidly being improved. At this exciting stage of research in high temperature superconductivity, it is extremely important to provide an opportunity for researchers from industry, academia, government and other institutions around the world to freely exchange information and thus contribute to the further advancement of research.
