High-angle annular dark-field imaging
Web8 de fev. de 2024 · One technique that is approximately linear is (high-angle) annular dark field, (HA)ADF-STEM. The observed contrast for this technique linearly images the square of the phase of the transmission ... High-angle annular dark-field imaging (HAADF) is an STEM technique which produces an annular dark field image formed by very high angle, incoherently scattered electrons (Rutherford scattered from the nucleus of the atoms) — as opposed to Bragg scattered electrons. This technique is highly … Ver mais Annular dark-field imaging is a method of mapping samples in a scanning transmission electron microscope (STEM). These images are formed by collecting scattered electrons with an annular dark-field detector.
