Zarenia M, Pereira JM, Peeters FM, de Aquino Farias G - Nanoscale Res Lett (2011)

Bottom Line: We investigate the effect of an external magnetic field on the carrier states that are localized at a potential kink and a kink-antikink in bilayer graphene.These chiral states are localized at the interface between two potential regions with opposite signs.PACS numbers: 71.10.Pm, 73.21.-b, 81.05.Uw.

We investigate the effect of an external magnetic field on the carrier states that are localized at a potential kink and a kink-antikink in bilayer graphene.

Figure 7: Energy levels of a kink-antikink profile in bilayer graphene as function of external magnetic field B0 for (a) and (b) . The other parameters are the same as Fig. 5.

Mentions: Figure 7 displays the energy levels of a kink-antikink potential as function of an external magnetic field for (a) and (b) . For the kink-antikink case, the overlap between the states associated with each confinement region allows the formation of Landau orbits. Therefore, in contrast to the single kink profile, the proximity of an antikink induces a strong dependence of the states on the external field.
