Fig. 4: Calculated band structure of 2L α-Sb.
From: Realization of unpinned two-dimensional dirac states in antimony atomic layers
a The band structure of 2L α-Sb calculated without the inclusion of SOC. b–e The calculated band dispersions along ‘cut1-4’, respectively. The Dirac points in the direction of \(\bar{{{\Gamma }}}\)-\({\bar{{{{{{{{\rm{X}}}}}}}}}}_{1}\) are marked by green arrows in d and e. f–j Same as a–e, but calculated with the inclusion of SOC. k The Brillouin zone of 2L α-Sb. The Dirac points in the case without SOC are marked by red dots. l Schematic diagrams showing the formation of px,y and pz bands.
