The availability of surface oxygen vacancies or electrons is often viewed as the defining factor for the reactivity of perovskite oxides. Two precisely controlled surfaces on SrTiO3(110) show strikingly different O exchange kinetics, which the authors ascribe to the flexibility of the surface polyhedra.
