Protected surface state in stepped Fe (0 18 1)

Abstract Carbon (C) surface segregation from bulk stabilizes the Fe(0 18 1) vicinal surface by forming a c(3 $$\sqrt{2}$$ 2 × $$\sqrt{2}$$ 2 reconstruction with C zig-zag chains oriented at 45° with respect to the iron surface steps. The iron surface electronic states as measured by high resolutio...
