| Citation | Nellist is a prize winning world leader in Atomic Resolution Transmission Electron Microscopy (STEM). His pioneering advances to explain materials properties by quantitative atomic resolution STEM include the experimental demonstration of electron ptychography for phase determination and atomic structure analysis, the development of a robust framework for quantitative interpretation ("atomic counting") of incoherent annular dark field (ADF) images of materials, and the simultaneous coherent electron ptychography and incoherent ADF imaging for detecting light and heavy elements in a sample, providing a low dose imaging technique. He has applied these new powerful structure and chemical analysis capabilities to previously inaccessible materials problems of technological importance, in catalysis, batteries, others involving beam sensitive soft materials etc. His theoretical work on the incoherence of ADF images constitutes a seminal advance in understanding, and has put the interpretation of ADF images on a firm basis. He contributed significantly to the development of a spherical aberration corrector for electron lenses, and to the theory and application of aberration corrected STEM for three-dimensional imaging and analysis by optical sectioning and confocal microscopy. His work is remarkable for combining seminal advances in technique with rigorous theoretical underpinning. |
