Abstract

Ultra-violet photoemission spectroscopy has been used in this project to investigate the changes in photoemission spectra across the order/disorder transition in Cu-Au alloys. Many obvious changes are observed in the valence band spectra of the different phases, particularly in the area of Au-related states. In Cu3Au, the binding energy of Au-4f core levels in the ordered phase are shifted from the pure metal value by an average of 0.46 +- 0.05eV to increased binding energy. In CuAu, the corresponding shift value in the ordered phase is 0.33 +- 0.05eV, also to increased binding energy. In both disordered Cu3Au and CuAu the value of the Au4f core level shift is reduced by 0.12eV from that of their ordered states. Some of the results are new, and others are in good agreement with previous studies.
