Atom-by-atom tomography

Dr. Stephan Gerstl (ScopeM and LMPT)

Come take a trip into nanostructural analysis capability by taking materials apart atom-by-atom. Atomic scale processes define the properties we witness at macroscales. Therefore we ultimately should characterize our materials near atomic scale to understand and improve them.  Combining high chemical sensitivity and 3-dimensional spatial resolution, atom probe tomography strives for this ideal characterization goal of identifying atoms in their place.  I will show how this is possible with research examples of alloys strengthened by their nanoclusters, semiconductor dopants’ influence, to diffusion zones in minerals. With the latest developments in the field of atom probe tomography, there are opportunities to open the characterization space for softer and even fluid based materials.
