Band structures of Cu0.05PdTe2 measured along three high-symmetry directions using the helium lamp ARPES. (a) Symmetrized Fermi surface of Cu0.05PdTe2. The locations of the three momentum cuts are marked as blue lines #1, #2, and #3. (b)–(d) Band structures measured along three high symmetry directions: (b) K – Γ – K ′ (cut 1), (c) M – Γ – M ′ (cut 2), and (d) K ′– M ′– K (cut 3). Their corresponding energy-second-derivative images are shown in panels (e)–(g), respectively.
