(a) Projection of the (001) surface Brillouin zone. a* and b* denote the reciprocal lattice vectors.(b) The surface band structure of LaSb along the high symmetry k-path (\(\bar{X}\)-\(\bar{M}\)-\(\bar{{\rm{\Gamma }}}\)-\(\bar{X}\)) as shown in (a). The Dirac point is encircled and is denoted by DP. Presence of odd number of gapless Dirac cones at the \(\bar{M}\)-point on the (001) surface suggests that LaSb may have a non-trivial topological character.
