Intrinsic spin-orbit coupling gap and the evidence of a topological state in graphene

Jonas Sichau, Marta Prada, Timothy J. Lyon +4

In 2005 Kane & Mele[C. L. Kane and E. J. Mele, Phys. Rev. Lett. 95, 226801 (2005)], predicted that at sufficiently low energy, graphene exhibits a topological state of matter with…
