Abstract：

Atomic-scale microscopy and microanalysis fundamentally drive basic advances in materials science, allowing for correlating materials and devices properties to their atomic structure and chemical composition. Atom probe tomography (APT) is a modern technique that is fast rising in prominence for nanoscale characterisation of structural and functional materials. APT relies on an intense positive electric field that induces the emission of individual atoms in the form of ions, from the surface of a sharp, sub-micron needle-shaped specimen. Treatment and reconstruction of the APT data results in a 3D point-cloud with near-atomic resolution, thereby providing insights into the composition of microstructural structural features such as precipitates, interfaces and grain boundaries which control the properties of materials.
After an introduction to the fundamentals of APT, I will showcase applications of the technique to a range of materials, with an emphasis on correlative approaches with electron microscopy.
