Far Ultraviolet Photoemission Studies of the Electronic Structure of Solids.

Abstract

Ultraviolet photoemission spectroscopy (PES) was used to study properties of solids over a wide energy range. A new type of PES spectrometer was designed and constructed so spectra at high energy could be obtained with synchrotron radiation from the storage ring at the University of Wisconsin. In the latter part of the program the spectrometer was modified so angle-resolved data was obtained. Quantum phenomena, not normally studied in UPES experiments, were investigated with the aid of two new PES data scans developed in this program. The scans called CIS and CFS frequently make it possible to observe emission properties which are very difficult to extract from the traditional energy distributions curve (EDC) data. The quantum properties determined in this program came from observing core and valence band (VB) excitations. In addition to direct emission for core excitations, the electrons generated by decay of the core holes were measured with CIS and CFS data.
