Abstract
Ultraviolet photoemission spectroscopy provides a powerful tool for studying both the bulk and surface electronic structure of solids. While previous photoemission studies of solids have concentrated on the electronic structure of filled electronic levels, i.e., the valence bands of semiconductors and the filled conduction bands of metals, the extension of this technique to study the dynamic transient processes experienced by electrons excited into otherwise unoccupied states has only begun to be exploited.1 We have constructed an experimental system that utilizes the generation of short pulse- width coherent vacuum-ultraviolet light to perform photoemission studies at solid surfaces and in the bulk.
