Unprecedented Precise Determination of the 3D Positions of Individual Atoms

Scientific Achievement

Using the Molecular Foundry’s TEAM I microscope, an international collaboration of users and staff measured the 3D coordinates of nine layers of atoms.

Significance and Impact

The 3D positions of single atoms were measured allowing identification of a point defect, the absence of a single atom. These defects can weaken materials, which is important for components of machines like jet engines.
