High angle annular dark field

Dark-field studies in transmission electron microscopy play a powerful role in the study of crystals and crystal defects, as well as in the imaging of individual atoms. Briefly, imaging involves tilting the incident illumination until a diffracted, rather than the incident, beam passes through a small objective aperture in the objective lens back focal plane. Dark-field images, under these conditions, allow one to map the diffracted intensity coming from a single c… Web26 de jul. de 2012 · Microstructures of epitaxial Ca 0.33 CoO 2 thin films, which were grown on m plane and c (0001) plane of α–Al 2 O 3 by the reactive solid-phase epitaxy (R-SPE) method and the subsequent ion-exchange treatment, were investigated in detail by using selected-area electron diffraction, high-resolution transmission electron microcopy, …
