Overview
- University of Victoria researchers report sub-ångström resolution on a compact scanning electron microscope using ptychography.
- The study, published October 14, 2025 in Nature Communications, demonstrates 0.67 Å resolution at 20 keV.
- The approach leverages computational reconstruction of overlapping electron-scatter patterns rather than relying on high-energy transmission electron microscopes.
- Lead author Arthur Blackburn cites immediate benefits for 2D materials research and future potential in nanotechnology and structural biology.
- The project involved Hitachi High-Tech Canada and received support from the Natural Sciences and Engineering Research Council of Canada.
