Abstract
In this review we describe the development of photoemission spectroscopy
(PES) from the first historic observations of the photoelectric effect
by Hertz and Hallwachs to state-of-the-art experiments. We present
several examples for the application of PES for chemical analysis
of solids (ESCA), the determination of the valence band structure
by angle-resolved photoemission (ARUPS), and the investigation of
many-body effects, in particular by high-resolution PES on the meV-scale.
Furthermore, we give a brief overview about the wide spectrum of
experimental methods based on PES.
