Fig. 3: Evolution of the band structure of TaTe4 with periodic lattice distortion (PLD).

a Band dispersions along the \(\bar{\Gamma }\bar{Z}\) direction measured at 40 K. The ARPES spectra measured by LH and linear-vertically (LV) polarized photons are summed together. b Zoom-in plot of the band structure in the CDW gap. c Calculated electronic structure of TaTe4 in the normal state. d–f Evolution of the calculated band structure along the ΓZ direction with increasing PLD magnitudes. The yellow and green lines in d are the bands along ΓZ. The red line in d is the band along XR which is folded to the ΓZ direction. Data in a and b were collected using 24.8 eV and 100 eV photons respectively.
