Abstract

Thin films of α-alumina have been produced by annealing oxide films produced by the thermal oxidation of aluminum substrates. Grains of αalumina which formed in the basal orientation show well-defined surface steps. When these steps move they interact with particles which have nucleated on the surface. Further annealing allows direct observation of the movement of these surface steps.
