Web1 de jan. de 2016 · Fig. 2 (a) is a representative dark field TEM image of 180° domains in PbTiO 3 (PTO). Vertical boundaries between the white and dark contrast in the first PTO layer indicate the 180° domain-walls, as marked with downward arrows. One of the 180° domain-walls is further magnified in AC-HAADF-STEM mode, as shown in Fig. 2 (b). WebDark-field microscopy(also called dark-ground microscopy) describes microscopymethods, in both lightand electron microscopy, which exclude the unscattered beam from the image. As a result, the field around the specimen (i.e., where there is no specimen to scatterthe beam) is generally dark.
