High-angle annular dark-field scanning

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. Ver mais • Transmission electron microscopy • Scanning transmission electron microscopy • Dark field microscopy Ver mais WebHAADF images are formed by collecting high-angle scattered electrons with an annular dark-field detector in dedicated scanning transmission electron microscopy (STEM) ... Specimen must be thin (<40nm) for most high resolution imaging applications. Samples can be prepared by chemical thinning, ...
