From: Three-dimensional flat bands in pyrochlore metal CaNi2

Extended Data Fig. 1

(a) Experimental geometry of VUV-ARPES. (b) The simulated trajectory of photoelectrons for the photon energy-dependent ARPES experiment. Photoelectron trajectories from 80 eV to 200 eV were plotted as red and green curves with 5 eV steps. Black solid lines correspond to the bulk Brillouin zones. 3D Brillouin zones truncated by (c) kx-kz plane at ky = 0, (d) kx-ky plane at kz = 0, and (e) kx-ky plane at kz = π/c.
