WebMar 3, 2024 · To accurately detect the high-symmetry direction and the high-symmetry plane, we varied photon energies to take ARPES data along the Γ-Z direction. As shown in Figure 2 C, the modulation of ARPES intensity enables us to determine the high-symmetry points in momentum space. Several points of high symmetry are of special interest – these are called critical points. [3] Other lattices have different types of high-symmetry points. They can be found in the illustrations below. See also [ edit] Brillouin-zone construction by selected area diffraction, using 300 keV electrons.
