Step by step...
Abstract:
Researchers at the Aono Atomcraft Project in Japan, using an STM, are now able to extract a single silicon atom from the surface of a silicon crystal and rebond it to the surface at a different location. Atoms translocated in this manner can be re-removed without disarranging the underlying atomic layers. Atoms brought from afar can be used to repair holes in the silicon surface, or they can be used to build structures on top of the surface.
