When the In2O3 surface is subjected to reducing conditions it responds with the formation of an ordered array of isolated In adatoms. The facile back-and-forth between the oxidized and reduced surface should allow tuning surface properties in a judicious and clear-cut manner. On a more fundamental level, the ordered adatom structure is an entirely novel way of any oxide surface to respond to reducing conditions.
