Graphene Band Gaps

Caption

The band structure of a representative three-dimensional solid (left) is parabolic, with a band gap between the lower-energy valence band and the higher-energy conduction band. The energy bands of two-dimensional graphene (right) are smooth-sided cones, which meet at the Dirac point.
