3-D Coordinates (IMAGE) University of California - Los Angeles Caption The 3-D coordinates of thousands of individual atoms and a point defect in a material were determined with a precision of 19 trillionths of a meter, where the crystallinity of the material is not assumed. The figure shows the measured 3-D atomic positions of a tungsten tip, consisting of nine atomic layers, labeled with crimson (dark red), red, orange, yellow, green, cyan, blue, magenta and purple from layers one (top) to nine (bottom), respectively.
