摘　　要：Graphene is an amazing material that presents us with new challenges and opportunities,even after two decades of extensive study.The two linear energy bands of graphene cross at the K and K’points of the hexagonal Brillouin zone with topological winding numbers±1.This Dirac cone description is nearly perfect within a~3 eV energy range—more than 100 times room temperature.Moreover,the chemistry of graphene sets its Fermi energy right at the Dirac points.
