Fig. 2: Calculated band structure of 1L α-Sb.
From: Realization of unpinned two-dimensional dirac states in antimony atomic layers
a The band structure of 1L α-Sb calculated without the inclusion of SOC. The bands are colored according to their orbital components. b, c The calculated band dispersion along 'cut1' and 'cut2' (marked in m) without the inclusion of SOC. d–f Same as a-c, but calculated with the inclusion of SOC. g–l Band structure (without SOC) of 1L α-Sb under uniaxial lattice strains along y-direction. g, j Band dispersion along 'cut1' and 'cut2' (marked in m) with − 4% lattice strain in \(\hat{y}\) direction. h, k and i, l same as g, j, but for lattice strains in \(\hat{y}\) direction of − 1% and +2%, respectively. m The Brillouin zone of 1L α-Sb. The Dirac points in the case without SOC are marked by the red dots. n The locations of Dirac points under uniaxial lattice strains of −4%,−1% and +2% in y-direction. The blue arrows indicate the movement of Dirac points as the lattice constant b increases.
