Physics of Dirac electrons in graphene

The graphene consisting of a monolayer graphite sheet was fabricated and the conductivity modulation by the gate was demonstrated and the quantum Hall effect was observed. Since then, various experimental and theoretical investigations have been performed to reveal its exotic electronic and transport properties. Actually, graphene has been a subject of theoretical study prior to the experimental realization because of the peculiar electronic structure also responsible for intriguing properties of carbon nanotubes. The purpose of this talk is to give a brief review on characteristic features of electronic states in graphene mainly from a theoretical point of view, together with some of representative examples of recent experiments.
