Figure 2: Bulk electronic structures and W1 type of Weyl cones in TaP.
From: Observation of Weyl nodes and Fermi arcs in tantalum phosphide
(a) Photoemission intensity of the bulk electronic states as a function of energy relative to Fermi level in the ky-kz plane. (b,c) The ARPES spectrum and the energy distribution curves along the high-symmetry lines Γ-Σ-S-Z-Γ. The calculated bands are overlaid on top of the spectrum in b for comparison. (d) Fermi surface map in the kx-ky plane at kz=±0.58 π/c’, taken with hv=478 and 520 eV. (e,f) ARPES intensity plot and its curvature plot with calculated bands overlaid on top. The data were acquired with hν=520 eV along cutx passing through W1. (g,h) Same as e and f, but the data were acquired with hν=478 eV. (i) Fermi surface map in the ky-kz plane at kx=0, the data were acquired with soft X-ray. (j,k) and (l,m) Same as g,h but along a long cuty and cutz, respectively.
