This book describes the status of photoelectron spectroscopic techniques, both theoretical and experimental, that have been applied to the study of the cuprate ('high-temperature') superconductors, together with the results derived from such measurements. 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 interpretation of such spectra and to the problems in obtaining good sample surfaces and high resolution. Some comparison with results from other experimental techniques is made. 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.

A survey of recent experimental results on copper oxide superconductors with transition temperatures from 30 K to above 120 K. Addresses the BCS theory, the electron-phonon interaction mechanism, and new theoretical models. Discusses sample preparation, and compares the copper oxide superconductors with transition metal and other superconductors.

“The Frontiers of Knowhledge (to coin a phrase) are always on the move. - day’s discovery will tomorrow be part of the mental furniture of every research worker. By the end of next week it will be in every course of graduate lectures. Within the month there will be a clamour to have it in the undergraduate c- riculum. Next year, I do believe, it will seem so commonplace that it may be assumed to be known by every schoolboy. “The process of advancing the line of settlements, and cultivating and c- ilizing the new territory, takes place in stages. The original papers are p- lished, to the delight of their authors, and to the critical eyes of their readers. Review articles then provide crude sketch plans, elementary guides through the forests of the literature. Then come the monographs, exact surveys, mapping out the ground that has been won, adjusting claims for priority, putting each fact or theory into its place” (J. M. Ziman, Principles of the Theory of Solids (Cambridge University Press, 1972) p.v). The main purpose of the book is to present the mechanism of - perconductivity discovered in 1986 by J. G. Bednorz and K. A. Müller, and to discuss the physics of superconductors. The last chapter of the book presents analysis of tunneling measurements in cuprates. The book is - dressed to researchers and graduate students in all branches of exact sciences.

The discovery of superconductivity at 30 K by Bednorz and Müller in 1986 ignited an explosion of interest in high temperature superconductivity. The initial development rapidly evolved into an intensive worldwide research effort - which still persists after more than a decade - to understand the phenomenon of cuprate superconductivity, to search for ways to raise the transition temperature and to produce materials which have the potential for technological applications. During the past decade of research on this subject, significant progress has been made on both the fundamental science and technological application fronts. A great deal of experimental data is now available on the cuprates, and various properties have been well characterized using high quality single crystals and thin films. Despite this enormous research effort, however, the underlying mechanisms responsible for superconductivity in the cuprates are still open to question. This book offers an understanding from the phase transition point of view, surveys and identifies thermal and quantum fluctuation effects, identifies material-independent universal properties and provides constraints for the microscopic description of the various phenomena. The text is presented in a format suitable for use in a graduate level course.
