Deskripsi
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.
