Much of the research in the literature has been focused on the size effect.
WebDark Field Computed Tomography (DFCT) is an advanced medical imaging technique that has gained prominence recently for its ability to provide high-contrast and detailed images of biological tissues. Traditional computed tomography (CT) scans rely on the attenuation of X-ray beams as they pass through the body, which can be limited in sensitivity and contrast … WebDark-field imaging mode, also called weak-beam (WB) technique here, is normally used for dislocation imaging. In addition to the applications mentioned above, dark-field TEM imaging is also a classical technique used to map strain variation in crystals when the thickness, composition and crystalline orientation are constant.
WebHigh-angle annular dark field (HAADF) scanning transmission electron microscopy (STEM) has become one of the most powerful tools to visualize material structures at atomic resolution. However, the parameter of electron microscope and sample thickness is the important influence factors on HAADF-STEM imaging.
