Present Status of Researches on Solid Surfaces by Means of Angle-Resolved Photsemission Spectroscopy

Abstract

Present status of researches on clean and adsorbed surfaces of solids by means of photoemission spectroscopy is briefly reviewed. Theoretical background developed in last decade is summarized very simply, in which the classical three-step-process is derived naturally from a view-point of recent one-step process as a special case. Some experimental results are shown as the examples for practical analyses of the data in order to get inf ormations about the electronic structures and also the atomic geometries on the surfaces. A shorthand bibliography for the experiments performed within last few years on this concern is given in the Appendix, where the papers are classified into the sample, surface net plane and adatoms.
