Layer- and orbital-resolved DFT calculation results of Fe(001)–p(1 × 1)-O along the Γ¯ –X¯ high symmetry line of the surface Brillouin zone. (a)–(c) Fe d_xz, (d)–(f) Fe d_{x² − y²}, (g)–(i) Fe d_{3z² − r²}, (j) O p_x, and (k) p_z. S and S-1 denote the topmost and second Fe layers for the d orbitals.
