The atomic-scale details are mostly unknown, however, and are often ascribed to poorly defined defects in the crystal lattice. Here we show that even thermodynamically stable, well-ordered surfaces can be surprisingly reactive. Specifically, we show that all the 3-fold coordinated lattice oxygen atoms on a defect-free single-crystalline r-cut (1-102) surface of hematite ({\\alpha}-Fe2O3) are exchanged with oxy","authors_text":"Cesare Franchini, Florian Kraushofer, Gareth S.
