Atom Probe Tomography: Basics and applications on complex sulphides

Atom Probe Tomography combines the three dimensional reconstruction of the lattice in real space with a time–of–flight mass spectrometer. The result is a tomographic image of the chemical composition of a solid sample making it a powerful technique to determine the chemical composition of nanostructures in 3-D with sub-nanoscale spatial resolution. It is a powerful technique to study processes on the near-atomic scale such as diffusion, exsolution, or the formation of nano-scale inclusions.
