ac, Schematics of 2D Dirac fermions and the corresponding Bloch-sphere representation of the wavefunction of filled states for the gapless case (a) and the gapped case with EF in (b) and out of (c) the gap. d, Fermi energy EF dependence of σxy for the case of a single massive Dirac fermion with gap Δ and Fermi velocity vF.
