From: Tunable band gap in few-layer graphene by surface adsorption
Band structures of Cu-adsorbed ABC-stacked trilayer graphene with the coverage of θ = (a) 1/16, (b) 1/9 and (c) 1/3 and (d) 1.
The red denotes the bands with weight projected on the metal outmost s valence band. The Dirac point of graphene in (b) and (c) is folded to the Γ point due to the reduction of the first Brillouin zone. The Fermi level is set to zero.
