PHOTOEMISSION-STUDIES OF HIGH-TEMPERATURE SUPERCONDUCTIVITY

Photoemission spectroscopy has recently emerged as one of the leading techniques in the study of high‐temperature superconductors. Relevant successes include the direct detection of the superconductivity gap, tests for departure from Fermi‐liquid behavior, and many interface chemical studies with technological interest. We present a review of the fundamental and applied aspects of this technique; the review is written for readers who are not specialized in electron spectroscopy or surface science.
