Figure 2

Constant energy contours on the (010) surface of \({\textrm{Gd}}{\textrm{Te}}_{3}\). (a) ARPES measured FS with a photon energy of \(\mathrm {90~eV}\). Experimental BZ is shown with red dashed lines. High-symmetry points and directions are labeled in blue color. (b–f) Energy contours at various binding energies as noted on top of each plot. (g) Calculated FS for non-CDW case. (h) Energy contour integrated within \(\mathrm {50~meV }\) window centered at \(\mathrm {300~meV}\) binding energy. ARPES data were collected at the SSRL end-station 5-2 at a temperature of \(\mathrm {8~K}\).
