Band structure and gaps of triangular graphene superlattices
arXiv:1006.0127 · doi:10.1098/rsta.2010.0214
Abstract
General properties of long wavelength triangular graphene superlattice are studied. It is shown that Dirac points with and without gaps can arise at a number of high symmetry points of the Brillouin Zone. The existence of gaps can lead to insulating behavior at commensurate fillings. Strain and magnetic superlattices are also discussed.
