The origin of this selectivity is explained by 2D morphology effects quantified by high-resolution scanning transmission electron microscopy in high-angle annular dark field mode (HR HAADF-STEM) and density functional theory (DFT) calculations.
Web12 de abr. de 2024 · Bright field, annular dark field (ADF), and high-angle annular dark field (HAADF) STEM imaging are primarily used for sample navigation and feature size measurement. STEM images up to one gigapixel can be acquired quickly (up to 10 Mpixels/sec) with the integrated scintillator-based bright field and ADF/HAADF detectors. 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 …
