Figure 44. Z-STEM image of a stacking fault in the (001) lattice plane.

Figure 44

Figure 44a is a Z-STEM image of a CdSe nanocrystal in the [001] orientation with an extra set of spots in between the atomic columns. The line profile in 44b shows that the peak intensities are well above the noise level. Figure 44c and 44d shows a model of this stacking fault from the [001] and [100] directions. The crystal lattice has shifted (yellow portion) in the (001) plane creating an ‘extra’ set of peaks in the image.
