Fig. 5: Contribution of the 1T CDW periodicity.

a Real-space lattice properties of the 2H-TaS2 phase, where the atomic and quasi-(3 × 3) CDW lattices are represented in gray and yellow, respectively. b Real-space lattice properties of the 1T phase, where the atomic and CDW lattices are represented in gray and cyan, respectively. c Reciprocal space representation of the combined 1T/2H system, following the same color code. The resulting CDW moire spots are represented in green. d Magnified reciprocal space representation following the same color code as in (c). The black half hexagon marks the 1T SBZ. The green dotted line corresponds to the lattice vector of the CDW moire and the green circles are the resulting moire spots after the symmetrization procedure. The red triangles mark the positions of the main K-K' intervalley features encoded in red in Fig. 4. The black dotted line corresponds to a lattice vector of the 1T CDW and also projects the red triangular features onto the edge of the SBZ, at the positions marked by the purple circles. e Superposition of the experimental QPI data and the band-selective JDOS calculations already presented in Fig. 4e with the additional marks of (d) overlaid on it.
