Band structures of (a) ZrTe, (c) WC, and (e) TaN without SOC. Those with SOC are correspondingly shown in panels (b), (d), and (f). The Fermi energy is set to 0 eV. (g) Band structure of ZrTe along the Γ–A line. Bands are labeled by their double group representations corresponding to D 3 h at Γ and A points and C 3 v on the Γ–A line. (h) and (i) Band structures in the (100) direction with k_z tuned to the TPs G₁ and G₂, respectively. (j) and (k) Projected surface density of states (SDOS) for the (010) surface of ZrTe with (j) Zr and (k) Te termination. (l) and (m) The (010)-surface Fermi surface of ZrTe at E = 0 eV for (l) Zr and (m) Te termination. Figure reused from Ref. [21].
