Main Results:

  • Observed surface structural transformations from metastable FeO(111) and O-terminated Fe(2)O(3)(0001) to Fe(3)O(4)(111) films.
  • The transformation pathway depended on oxygen pressure, substrate temperature, and annealing temperature.
  • Identified specific conditions for forming different iron oxide phases.

Conclusions:

  • Experimental observations provide insights into the surface structural evolution of iron oxides.
  • Model iron oxide surfaces, especially O-terminated ones, are valuable for further research in chemical reactions like catalysis.
