About Ca4Bi6O13

Ca4Bi6O13 is a complex oxide composed of calcium, bismuth, and oxygen. As a thermodynamically stable phase located on the convex hull, it represents a robust crystalline arrangement that is well-supported by existing structural data. Its electronic character is defined as semiconducting, making it an interesting subject for studies involving electronic transport and oxide-based functional materials. The compound is characterized by a significant degree of structural diversity, as evidenced by multiple reported configurations across various databases. This structural richness suggests a versatile framework that may be tuned for specific physical properties through compositional or structural modifications. It serves as a valuable entry point for researchers investigating the interplay between heavy metal cations and alkaline earth metals in oxide lattices.
