a Top: Schematic of the crystal structure. Bottom: Top view of the px (green) and pz (purple) orbitals in the squared Te planes. The arrows indicate the orbital coupling along (t∥) and perpendicular (t⊥) to the chains. b Fermi surface contours near the Fermi energy measured by 7-eV and 6-eV laser. The green and purple lines correspond to the px and pz orbitals calculated with the tight-binding model, respectively. The black arrow indicates the CDW wavevector. Shadow bands (SB) and folded bands (FB) are noted. c Equilibrium electronic structures at an equilibrium temperature of 4 K by 7-eV laser. d Nonequilibrium electronic structures with a pump fluence of 0.64 mJ/cm2 at selected delay times.
