Figure 4
(a) Rashba-splitting of the Shockley surface state of Au(111) at the Fermi energy measured at 300 K with a magnification setting of M4 and an extractor voltage of 10 kV. (b) Energy dispersion of the surface state obtained at Ky = 0 slicing through the data shown in (a). (c) Intensity profile at Ky = 0 fitted to a Voigt function (red solid line) with 0.0172 Å−1 Gaussian broadening and the Lorentzian contribution (dashed line).
