Figure 36. CdSe Orientations.
Like TEM, the patterns seen in the Z-STEM images can be related to a CdSe model in the same orientation. The intensity seen in the Z-STEM images is directly related to the nanocrystal’s atomic structure. This allows for a simple comparison between the Z-STEM image and a nanocrystal model to identify the observed orientation. Figure 36a and 36b are high-resolution images of CdSe in the [100] and [001] orientations.
