Figure 1

(a) A schematic view of the transformation of Sb/Bi buckled honeycomb into a planar honeycomb. The plot gives buckling height as a function of lattice constant for the Sb honeycomb. Top view of the buckled honeycomb structure and the associated 2D Brillouin zone and high symmetry points are also shown. The atoms of two different colors mark atoms in the two different planes of the buckled structure. (b–f) give the band structures over a wide range of lattice constants.
