Fig. 3: Surface spectral functions of NdBi.
From: Unconventional surface state pairs in a high-symmetry lattice with anti-ferromagnetic band-folding
a nonmagnetic (NM) (001) along \(\bar{\varGamma }\)-\(\bar{X}\)-\(\bar{{M}^{{\prime} }}\) and (b) 2q (001) along the equivalent direction of \(\bar{\varGamma }\)-\(\bar{X}\)-\(\bar{\varGamma }\). The green dots indicate the original band inversion region along \(\bar{\varGamma }\)-\(\bar{X}\), just above the bulk hybridization gap and the associated unconventional surface state pairs. Surface spectral functions on (c) 3q (001), (d) 2q (001), (e) 2q (010) and (f) 1q (110) along other directions. 2D surface Fermi surfaces at two different energies as labeled in eV with respect to Fermi energy (EF) for four surfaces: (g, k) for 3q (001), (h, l) for 2q (001), (i, m) for 2q (010), and (j, n) for 1q (110), respectively. (o, p) are the averaged cubic {001} domains for 2q and 1q, respectively. Blue, white and red colors stand for low, medium, and high density of states.
