WebHere we show, for the first time, that the structure factor phases can be also obtained from high angle annular dark-field (HAADF)-STEM images and used for 3D reconstruction of atomic structures. This is applied to the complex zeolite structure, silicalite-1 (Formula SiO 2, framework code MFI, Pnma, a = 20.090 Å, b = 19.738 Å and c = 13.142 Å). WebWidely available image processing techniques are applied to high-angle annular dark field (HAADF) images of atomic columns to precisely locate their positions and the material's lattice constant (s). This ideology has …
