From: Large spin splitting of metallic surface-state bands at adsorbate-modified gold/silicon surfaces
Effect of adsorbate species.
(a) Fragments of the ARPES spectra taken in the 
direction near the Fermi level of the Tl-, In-, Na- and Cs-adsorbed 
surfaces. (b) Momentum splitting at the Fermi level Δk|| plotted as a function of the Fermi wave vector kF for 
and 
bands measured for various species (as indicated in the graph). (c) Calculated band structure along the 
with the experimental dots from (b) superposed on the 
and 
dispersion curves. Surface state bands are shown by filled yellow circles, shaded region indicates projected bulk bands. Range of the varied Fermi level position is indicated by the pink shaded area.
