Figure 6
Gold Fermi edge spectra collected at ∼2, ∼4 and ∼6 keV using Si(111), Si(311) and Si(333) reflections for the exciting photon beam, respectively. Open circles show the experimental data and solid red lines the fits. Excitation energies, the used crystal planes, and the combined experimental resolution (beamline plus electron analyzer) as derived from the fit are given for each spectrum. |
