Figure 1. Directions of the angle-resolved photoelectron spectroscopy (ARPES) measurements (a) for wide angle overview scans in ΓK and ΓM directions of the graphene Brillouin zone at this figure and (b) for the region near the K-point in Figure 2. ARPES spectra for the Graphene/Au/Ni system for (c) as prepared sample and (d) a sample exposed to atmosphere and subsequently annealed.
