Extended Data Fig. 2: Electronic structure of the S-breaking and S-preserving surfaces of MnBi2Te4.
From: Prediction and observation of an antiferromagnetic topological insulator
a, b, Surface electronic bandstructure of MnBi2Te4 calculated for the (0001) (S-breaking; a), and \((10\bar{1}1)\) (S-preserving; b) terminations using the ab-initio-based tight-binding approach. The regions with a continuous spectrum correspond to the three-dimensional bulk states projected onto a two-dimensional Brillouin zone.
