The technique allows for the observation of low Z-elements, such as oxygen, using a bright contrast and dark background with a higher signal to noise ratio when compared to competing techniques such as annular bright field STEM (ABF-STEM) . As STEM imaging is inherently two-dimensional, determining a definitive space group for B6TFMO using this characterization technique is challenging. However, information about the BO6 tilting can be gained by imaging the system in multiple crystal orientations. In this study, iDPC-STEM imaging is employed to visualize the distribution of light oxygen atoms across different layers within the Aurivillius phase.
