High-angle annular dark-field haadf images
WebHIGH ANGEL ANNULAR DARK-FIELD (HAADF) MICROSCOPY HAADF images are formed by collecting high-angle scattered electrons with an annular dark-field detector in dedicated scanning transmission electron microscopy (STEM) instruments. The contrast of HAADF images is (a) strongly dependent on the average atomic number of the scatterer Web14 de nov. de 2024 · TEM high-angle annular dark-field (HAADF) images of a single NW implanted using a fluence of 1 × 10 15 at/cm 2 and annealed at 1000 °C are shown in Figure 6. HAADF imaging is sensitive to the atomic number of the material (Z-contrast), thus the dark spots visible in Figure 6 a are signs of thinner sample areas.
