Implication

Spectroscopic analysis demonstrates relativistic density-of-states alignment in single-crystal gold valence bands, indicating minimal matrix-element modulation above 40 electron volts.

Key Points

To measure high-resolution valence-band photoemission spectra of gold and evaluate the accuracy of theoretical relativistic band-structure models.
Obtained photoemission spectra from a single-crystal gold specimen irradiated with monochromatized Al Kα radiation.
Applied background and scattering corrections to raw experimental spectra prior to direct comparison with broadened theoretical density-of-states calculations.
Relativistic band-structure calculations, including Korringa-Kohn-Rostoker and relativistic-augmented-plane-wave models, matched experimental density-of-states profiles closely after broadening.
Theoretical models using full Slater exchange yielded the closest fit to experimental data, whereas fractional exchange (2/3 or 5/6) produced d bands that were excessively wide.
Spectral similarity between the x-ray measurements and 40.8-eV ultraviolet spectra demonstrated minimal photon energy dependence above 40 eV and an absence of strong matrix-element modulation.
