From: Tunable band gap in few-layer graphene by surface adsorption
(a) Band structure and (b) electron distribution on the uppermost layer graphene of Al-adsorbed ABA-stacked trilayer graphene with the coverage of θ = 1/3. The blue and red lines denote the bands with weight projected on the Al 3p and 4s-derived bands, respectively. The Dirac point of graphene is folded to the Γ point due to the reduction of the first Brillouin zone. The Fermi level is set to zero.
