Fig. 9: Density of states for trigonal strain.
From: Quantized valley Hall response from local bulk density variations
Total density of states ρ(ε) (DoS) in the hexagonal flake for strain intensities (a) τ > 0 and (b) τ < 0. Dashed gray lines indicate the energy of the analytical pseudo-Landau levels \({E}_{\nu }=\pm {v}_{F}\sqrt{2\hslash e| {{{{{{{{\bf{B}}}}}}}}}_{\tau }^{\xi }| \nu }=\pm t\sqrt{3| \tau | \nu }\) for ν = 0, 1, 2, 3, 4, where vF is the Fermi velocity, \({{{{{{{{\bf{B}}}}}}}}}_{\tau }^{\xi }\) the pseudo-magnetic field at valley ξK and ξ is the valley index ( ± 1). c, d Specific cuts of panels (a) and (b) (marked with a vertical dashed blue line) for ∣τ∣ = 0.07, respectively. Solid gray lines denote the analytical pseudo-Landau levels.
