Bright-field tem image
WebIt is important to mention that in general this phenomenon, showing contrast reversal in the bright-field image, could cause misinterpretations of bright-field images of mixed-phase specimens where the spatial distribution of different materials is unknown. Figure 2881. Dark-field (a) and bright-field (b) STEM images of a diamond/Si interface ... 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 annular dark-field detector. For optimum HAADF imaging, the TEM/STEM must have a high maximum diffraction angle, small minimum camera length, and a descanning facility.
