Sublattice degree of freedom
WebThe sublattice symmetry reads σ z H 0 ( k) σ z = − H 0 ( k). Sublattice symmetry is only approximate, and it is consequence of the nearest neighbor tight-binding model. Just like the inversion symmetry mentioned in the video, it protects the Dirac points and needs to be broken in order to open a gap. Web11 Apr 2024 · τ i (i = x, y, z) is the pseudospin Pauli matrix for two sublattice degrees of freedom. To solve the transmission problem of the NG/SG junction, as shown in Fig. 1(a) , we assume that an incident electron with incident angle θ is injected into the graphene-based normal layer at η valley with spin ρ σ .
