VHS points near the Fermi level and their characters for a YRu3Si2, c CsV3Sb5, and d ScV6Sn6. The band structure of the parent phase of each compound is shown, projected onto the d orbitals of the V or Ru atom, with the radius of the open circles proportional to the projected weight. The charge density of VHS points is displayed, where m-type and p-type refer to sublattice-mixed and sublattice-pure types, respectively. b Unfolded band structure of the charge-ordered phase in YRu3Si2. See also the band structure without band unfolding in Supplementary Fig. S2. In the inset, the solid line indicates the BZ of the parent P6/mmm structure, while the dashed line indicates the BZ of the charge-ordered Pmma structure.
