17. The simulations show that the energy of the γ′-Fe4N slab with an Fe-terminated surface is lowered 0.6eV/surface atom, if 0.5 ML of N are adsorbed on the surface. N produces indeed a c(2×2) superstructure on Fe(100) at saturation as shown, e.g., by R. Imbihl, R.J. Behm, G. Ertl, and W. Moritz, Surf. Sci.
