Figure 4
The px and py orbital-selective spin textures of Bi3Te4I at the upper (a) and lower (b) Dirac cone for I-terminated surface and (c) the upper Dirac cone for Te-terminated surface, respectively.The corresponding pz orbital-selective spin textures are shown in (d), (e) and (f). More red and blue colors in (a)–(c) denote more px and py character respectively, while more red colors in (d)–(f) denote more pz character. The surface states in the energy range of −0.1 eV ~ 0.2 eV are used for the orbital projections. The black arrows represent the total in-plane spin textures related to the corresponding orbitals.
