Abstract Details: Because of its atomic thickness and elastic properties, electronic structure of graphene can be significantly modified with external perturbations. In this talk, I will discuss some theoretical models constructed to capture changes in the band and Landau level structure in (mono- and bilayer) graphene due to strain, external electric field and presence of a substrate. In particular, I will talk about strain-induced changes in the topology of the low-energy band structure of bilayer graphene and signatures of pseudo-magnetic field in electronic transport through strained graphene ribbons. I will also discuss formation of minibands in graphene on incommensurate hexagonal substrates (e.g. h-BN) and some peculiarities of the band structure of bilayer graphene in strong perpendicular electric fields.Click HERE for directions
