Observation of Landau levels of Dirac fermions in graphite

The unique electronic behaviour of monolayer and bilayer graphene(1,2) is a result of the unusual quantum-relativistic characteristics of the so-called 'Dirac fermions' (DFs) that carry charge in these materials. Although DFs in monolayer graphene move as if they were massless, and in bilayer graphene they do so with non-zero mass, all DF...更多
