Figure 5: Calculated slab band structure in comparison with the measured band structure.
From: Dirac cone protected by non-symmorphic symmetry and three-dimensional Dirac line node in ZrSiS
(a) Bands along ΓX. The orange bands indicate how bands are progressing, showing the hybridization of the surface-derived state with the bulk. (b) Bands parallel to ΓX highlighting the mixing of surface-derived states and bulk bands belonging to the cone at X. (c) Slab band structure along ΓM, showing that there is no big change to the bulk band structure in this direction. (d) Bands along MXM, surface-derived bands are highlighted in orange. The surface states significantly reduce the bulk gap along this direction.
