From: Tuning the Fermi velocity in Dirac materials with an electric field
(a) DFT-calculated band structure of an N = 5 aGNR with (red) and without (black) a transversal electric field F = 0.51 V/Å. (b) Variation of the Fermi velocity of the first conduction band as a function of the electric field. We have considered the slope for the linear bands between k ~ 0.1 × 2π/a and k ~ 0.2 × 2π/a.
