Reduced dimensional ferroelectric domains and their characterization techniques

Figure 8. Emergence of ferroelectricity in ultrathin films of otherwise non-ferroelectric SrTiO3. (A) Schematics illustrating the effect of polar nanoregions based on thickness. In thicker films, polar nanoregions are not effectively aligned, whereas in thinner films, they align well. (B) Inverted ABF-STEM image and corresponding polarization mapping. Polar nanoregions are well visualized. Reproduced with permission[14]. Copyright 2015, American Association for the Advancement of Science.
