From graphene to graphite: Electronic structure around theKpoint

Abstract: Within a tight-binding approach we investigate how the electronic structure evolves from a single graphene layer into bulk graphite by computing the band structure of one, two, and three layers of graphene. It is well known that a single graphene layer is a zero-gap semiconductor with a linear Dirac-like spectrum around the Fermi energy, while graphite shows a semimetallic behavior with a band overlap of about 41 meV. In contrast to a single graphene layer, we show that two graphene layers have a parabolic spe… Show more

“…Because the various physicochemical properties of graphene are sensitive to its thickness [3][4][5] , the capability of synthesizing uniform graphene with well-controlled layer numbers has been one of the major challenges in graphene research 6 . Chemical vapour deposition (CVD) has been actively investigated since 2009 for growing graphene on catalytic metal films or foils from gaseous carbon sources at high temperatures [7][8][9][10] .…”

“…32 On the one hand, there are more relevant parameters than in monolayer or bilayer graphene because of the presence of next-nearest layer couplings; on the other hand, a lack of translational invariance in the direction of layer stacking means that the number of basis states in the model is 2N , not four as in the Slonczewski-WeissMcClure model of bulk graphite. 32 Although multilayers with a moderate number of layers, N 10, are thought to be similar to bulk graphite, 33 the properties of few-layer graphene (typically N 3) are distinct. 29,[33][34][35][36][37][38][39][40][41][42][43][44][45][46][47][48][49][50] Here, we consider ABA-stacked (Bernal) multilayer graphene and analyze its Landau level spectrum and quantum Hall conductivity in magnetic fields.…”

“…It has been pointed out that ML, BL, and TL graphenes show different electronic properties, and the electronic structure rapidly evolves with the number of layers, approaching the three-dimensional limit of graphite at ~10 layers [55]. Thus, identification of the number of graphene layers, i.e., determination of the thickness of a graphene sample, is essential for informed research and distinct applications.…”
