Upon deposition of Cu on a 1 × 1 α-Al_{2}O_{3} (0001) surface at room temperature the surface structure was found to change with increasing amounts of Cu deposited, from two-dimensional monolayer islands through three-dimensional nuclei until reaching a thin film. Subsequent surface heat-treatment to 650°C produced a stable Cu(111)-R30° superstructure as observed by LEED.
