Influence Of Magnetic Field On The Electronic Properties Of Graphene

Graphene is single atomic layer separated from graphite, an idealtwo-dimensional system. Graphene is of the special electronic structure.With strongvertical magnetic field, the Quantum Hall Effect of graphene is different from theother two dimensional metal electronic. Studying the electronic properties ofgraphene in strong magnetic field of is necessary.The paper will calculatetheoretically the transformation mechanism of electronic properties and conductor-semiconductor in the Fermi energy of graphene with the different magnetic field.Thepaper will be divided into three chapters.Chapter Ⅰintroduct the background of graphene.Include basic properties andcrystal structure of it.Chapter Ⅱpresent the theory method of this paper.The paper will usenon-equilibrium green’s function method which is based on the tight-binding theory.Chapter Ⅲdiscuss the influence on the electronic properties.
