Figure 3

Experimental observation of CDW induced gap. (a) Dispersion map and (b) its second derivative along the \(\mathrm{\overline{M}}-{\overline{\Gamma}}-\mathrm{\overline{M}}\) direction. (c) Energy distribution curve integrated within the momentum window represented by magenta line in (a) and the Fermi edge fit. (d) Dispersion map and (e) its second derivative along the \(\mathrm{\overline{Z}}-{\overline{\Gamma}}-\mathrm{\overline{Z}}\) direction. (f) Energy distribution curve integrated within the momentum window represented by the magenta line in (d) and the Fermi edge fit. (g) Experimental dispersion map along the \(\mathrm{\overline{X}}-{\overline{\Gamma}}-\mathrm{\overline{X}}\) direction. (h) Experimental band structure along \(\mathrm{\overline{M}}-\mathrm{\overline{X}}-\mathrm{\overline{M}}\). Data were collected at the SSRL beamline 5-2 at a temperature of \(\mathrm {8~K}\).
