Fig. 1: Crystal structure and Fermi surface of ZrTe\({}_{3}\).
From: Distinction between pristine and disorder-perturbed charge density waves in ZrTe3
a The crystal structure. b The first Brillouin zone. c Calculated Fermi surface (see Methods) at \({{\bf{q}}}_{{{\bf{c}}}^{* }}=0\). d Illustration of Fermi surface nesting properties. The Fermi surfaces indicated in red and blue are relatively flat sheets that run along the \({{\bf{c}}}^{* }\) direction perpendicular to the plane of display. Solid and dashed lines in d refer to the Fermi surfaces at \({{\bf{q}}}_{{{\bf{c}}}^{* }}=0\) and \({{\bf{q}}}_{{{\bf{c}}}^{* }}=0.33\), respectively, where the difference indicates Fermi surface warping along \({{\bf{c}}}^{* }\). The electronic gap associated with the CDW order opens from the shaded region around the D-point. The orange and cyan arrows indicate slightly different nesting wave vectors along \({{\bf{a}}}^{* }\) (with fixed 0.33 r.l.u. along \({{\bf{c}}}^{* }\)) on different parts of the Fermi surfaces.
