Web29 de out. de 2013 · This method has the advantage that we can routinely quantify annular dark field images operating at both low and high beam currents, and under high dynamic range conditions, which is useful for the quantification of ultra-thin or light-element materials. 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.
