Abstract

The Synchrotron Storage Ring at the Physical Sciences Laboratory of the University of Wisconsin was used as a source of ultraviolet radiation for performing photoemission spectroscopy on Bi2Te3 and Sb2Te3. A structure plot is made and a model density of states (DOS) is derived from the experimental data for Sb2Te3. UPS data was used to observe in Bi2Te3 optical excitation from 5d core states to conduction-band states below the direct-emission threshold by observing the Auger decay of 5d core holes. Maxima in the spectral dependence of the Auger emission in Bi2Te3 are observed, which are explained in terms of maxima in the core-conduction-band joint density of states.
