    • In all DFT calculations the distance between the graphene planes was 20 a.u., the Brillouin zone integration was performed using an uniform k-point grid 36 - 36 - 1, with the functional of ref 47, plane waves (60 Ry cut-off) and pseudopotentials, (48) using the PWSCF code. (49) An electronic smearing of 0.02 Ry with the Fermi?Dirac distribution was employed.

    • Non-self-consistent GW calculations have been performed starting from DFT-LDA wavefunctions, using a plasmon pole approximation, following the scheme of Hybertsen and Louie, (35) with the code YAMBO. (50) We use a 36 - 36 - 1 k-point grid for the primitive cell and an equivalent one for the supercell. Convergence in the number of bands and size of the dielectric constant has been carefully checked.

    • We suppose that is the case also in multilayer graphene, althougt the band structure is different from that graphene, a result similar to the one we found for graphen holds, as we found for graphite. (27)
