Figure 2

Band structure with SOI (red solid lines) and without SOI (black solid lines) of (a) TaAs, (b) TaP, (c) NbAs, and (d) NbP along high-symmetry lines in the bct BZ in Fig. 1b. The Fermi energy ε F (black horizontal line) is chosen as energy zero. In addition, the DOS (black lines) and the orbital-symmetry-resolved DOS (Ta6s and Nb5s: red lines, Ta5d and Nb4d: blue lines, and As4p and P3p: green lines) are plotted.
