LEED images of clean Fe(001) (a) and Fe(001)–p(1 × 1)-O (b) taken at the electron kinetic energy of E_K = 39 eV. (c) Surface Brillouin zone. The ARPES image plots of clean Fe(001) with the p-polarization geometry (d) and s-polarization geometry (e) taken at hν = 55 eV. The ARPES image plots of Fe(001)–p(1 × 1)-O with the p-polarization geometry (f) and s-polarization geometry (g) taken at hν = 55 eV. The dashed lines are guides to the eyes.
