Figure 1

(a),(b) ARPES intensity of the graphene $\pi$ band along the $p\Gamma K$ direction in $\mathrm{gr}/\mathrm{Ir}(111)$ (a) and $\mathrm{Ir}/\mathrm{gr}/\mathrm{Ir}(111)$ (b). (c),(d) Corresponding EDCs plots. (e) $\mathrm{C}\mathrm{\text{−}}1s$ core levels for an Ir coverage of $\theta =0.15\pm 0.05\mathrm{ML}$. Inset: Zoom on the $\mathrm{C}\mathrm{\text{−}}1s$ peak showing a shift of $30\pm 30\mathrm{meV}$ after the cluster growth. (normal emission, photon energy 450 eV) (f) Energy distribution spectra from $\mathrm{gr}/\mathrm{Ir}(111)$ and $\mathrm{Ir}/\mathrm{gr}/\mathrm{Ir}(111)$ measured at the $M$ point of the second Brillouin zone. Inset: The top of the $\sigma$ band shifts by $30\pm 30\mathrm{meV}$ after the cluster growth.
