Magnetic structure at zigzag edges of graphene bilayer ribbons
Eduardo V. Castro, N. M. R. Peres, J. M. B. Lopes dos Santos
We study the edge magnetization of bilayer graphene ribbons with zigzag edges. The presence of flat edge-state bands at the Fermi energy of undoped bilayer, which gives rise to a s…
Gaped graphene bilayer: disorder and magnetic field effects
Eduardo V. Castro, N. M. R. Peres, J. M. B. Lopes dos Santos
Double layer graphene is a gapless semiconductor which develops a finite gap when the layers are placed at different electrostatic potentials. We study, within the tight-biding app…
Low density ferromagnetism in biased bilayer graphene
Eduardo V. Castro, N. M. R. Peres, T. Stauber +1
We compute the phase diagram of a biased graphene bilayer. The existence of a ferromagnetic phase is discussed with respect both to carrier density and temperature. We find that th…
Localized states at zigzag edges of bilayer graphene
Eduardo V. Castro, N. M. R. Peres, J. M. B. Lopes dos Santos +2
We report the existence of zero energy surface states localized at zigzag edges of bilayer graphene. Working within the tight-binding approximation we derive the analytic solution…
