Rh on α-Fe₂O₃(1102) stabilized by coadsorbed water. (a) ncAFM image acquired at liquid He temperature of 0.05 ML Rh on α-Fe₂O₃(1102), deposited at room temperature in a partial pressure of 2 × 10^–8 mbar H₂O, then heated to 80 °C to desorb all water not coordinated to Rh. (b) Schematic model (top view) for the features indicated by green arrows in a. Rh adatom (gray) is stabilized by two OH groups (O_water in blue, hydrogen in white). Zigzag rows of surface oxygen are marked in blue in both panels. Orange arrow highlights a third protrusion that is sometimes present, which was attributed to an additional water molecule atop a surface Fe and hydrogen bonded to one of the OH groups.
