a Comparison of ARPES and DFT band structure (red) and Brillouin zone schematics for the probed high symmetry lines. The faint dispersive features around the Fermi level are artifacts originating from satellite lines of the non-monochromatized He–I radiation (see “Methods” section). The inset shows the dispersive behavior at the K-point on a strongly enlarged momentum scale, illustrating the deviation from an ungapped Dirac double-cone. b Detailed analysis of the K-point dispersions. The orange markers indicate the peak positions obtained from the peak fitting of the EDCs at selected k-vectors. c EDC at the K-point (red) and its peak-fit (blue—sum, orange dashed lines—peaks) accounting for the first two valence band states (VB, VB-1) and the lowest conduction band (CB).
