Abstract

The growth of small Ru, Rh and Sn crystals, atomic column by atomic column, has been recorded in real time using a 400 kV high-resolution electron microscope, operated in the surface profile imaging mode. A common observation preceding the addition of a new atomic plane on the surface of the small (2-4 nm) metal crystal was the occurence of a diffuse "cloud". Moreover, the sequential growth of an atomic plane was often preceded by the presence of such a cloud at the growth front (especially for Ru and Rh). Real-time video sequences showed that the addition of a new atomic layer typically took about 1 min.
