【 摘 要 】

Achievement of atomic-resolution electron-beam tomography will allow determination of the three dimensional structure of nanoparticles (and other suitable specimens) at atomic resolution. Three dimensional reconstructions will yield 'section' images that resolve atoms overlapped in normal electron microscope images (projections), resolving lighter atoms such as oxygen in the presence of heavier atoms, and atoms that lie on non-lattice sites such as those in non-periodic defect structures.
