(a) Along the ()-direction of the substrate and (b) 47° rotated against the -direction. The dashed black curves represent the dispersion of the LUMO and of the HOMO as calculated by density functional theory (see Fig. 2b. The horizontal line at binding energy EB=1.5 eV indicates a change in the normalization procedure between the LUMO and the HOMO region (see Supplementary Note 1 for details).
