Flat edge modes of graphene and of Z(2 )topological insulator
A graphene nano-ribbon in the zigzag edge geometry exhibits a specific type of gapless edge modes with a partly flat band dispersion. We argue that the appearance of such edge modes are naturally understood by regarding graphene as the gapless limit of a Z(2 )topological insulator. To illustrate thi...
