摘要：

The search for superconductors, catalysts, and semiconductors can be facilitated by an understanding of the relationship between the structure of a material and its properties. In this study, high‐resolution electron microscopy (HREM) is used to examine the structures of solid solutions of BiTaO materials including Aurivillius phases, and it is shown that the band gaps of the materials depend on the superstructure rather than on composition.
