Stable α‐Fe 2 O 3 surfaces : A 3D rendering of the controlled nanoscale morphology observed on a hematite (0001) surface is shown in the Figure. This atomically flat surface is characterized by circular depressions with diameters on the order of hundreds of nanometers and depths of 2.2 ± 0.2 Å. At room temperature, the surface is exceptionally stable, with no measured change following storage in air over several months.
