Abstract
Modern science and technology rely on functional materials, and the physical properties of these materials often strongly depend on defects, local disorder, nanoscale heterogeneities, and grain structures at the atomic scale. Atomic electron tomography (AET) is now able to locate the 3D coordinates of individual atoms and their dynamics with picometer precision and elemental specificity. However, the majority of AET results have been based on incoherent imaging methods, which limit the application of AET for radiation-sensitive materials and light chemical elements. In this talk, I will briefly discuss the current capability of AET and introduce ideas based on quantitative phase imaging to enhance dose efficiencies and enable the detection of light elements [1].
