High-resolution angle-resolved photoemission study of oxygen adsorbed Fe/MgO(001) |
Fermi surface mappings of clean Fe(001) (a) and Fe(001)–p(1 × 1)-O (b) taken at hν = 55 eV. The figures in red (top panel) and blue (bottom panel) color scale were taken with the p- and s-polarization geometries, respectively. The dashed lines are guides to the eyes. |
