THE ELECTRONIC STRUCTURE OF HIGH-T_c SUPERCONDUCTORS: INTRODUCTION AND RECENT STUDIES OF MODEL COMPOUNDS

摘要

An introduction into the electronic structure of high-T_c superconductors is given. This introduction is illustrated by recent studies of model compounds containing Cu-O planes, ladders and chains, performed using high-energy spectroscopies such as photoemission, x-ray absorption and electron energy-loss spectroscopy.
