Scientific Achievement
A single Si atom is deterministically placed and moved within a graphene lattice, with atomic-scale precision.
Significance and Impact
The ability to build materials and devices atom-by-atom is a long-held dream for materials science and device fabrication. These results move us one step closer to making it a reality.
Research Details
- A scanning transmission electron microscope (STEM) is used to simultaneously image and manipulate matter at the atomic scale.
- A single Si atom is inserted into a deterministically created vacancy within a sheet of graphene.
- A substitutional Si atom is moved within the graphene lattice onto a predefined lattice position.
