Fig. 3

a Crystal structure with the mirror plane marked in grey. b Valence band structure along the high-symmetry path; the band gap is 0.34 eV. c Constant energy surface at E = −50 meV. d–f Spin texture of the topmost valence band at the ΓYX plane, marked as yellow in panel (c). The constant energy contours correspond to E = −50 meV.
