WebThe technique of high‐angle annular dark‐field (HAADF) imaging, which is highly sensitive to atomic‐number contrast, can be performed on TEM/STEM systems using the standard … 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 sensitive to variations in the atomic number of atoms in the sample (Z-contrast images). For elements with a higher Z, more electrons are scattered at higher angles due to greater electr…
