Dirac semimetal: Transport by massless fermions

This is a 3D analogue of graphene and its unusual band dispersion leads to the electrons around the Fermi energy to behave like highly relativistic particles. Currently, intrinsic Dirac semimetals are Cd3As2 and Na3Bi. We design extrinsic Dirac semimetals from trivial and nontrivial insulators by tuning their bulk gap.
