Continuum models for twisted bilayer graphene: the effects of lattice deformation and hopping parameter

30 Apr 2019 Guinea Francisco Walet Niels R.

We analyze a description of twisted graphene bilayers, that incorporates deformation of the layers due to the nature modern interlayer potentials, and a modification of the hopping parameters between layers in the light of the classic Slonczewski-Weiss-McClure parametrisation. We shall show that flat bands result in all cases, but that their nature can be rather different... (read more)
