· Ba3Bi2TeO9

Ba3Bi2TeO9 is a mixed-metal oxide semiconductor compound containing barium, bismuth, and tellurium elements. This is an experimental/research material primarily investigated for its potential in thermoelectric and photocatalytic applications, belonging to the broader family of complex oxides used in solid-state device research. The material's notable characteristics stem from its layered perovskite-related structure, which influences its electronic transport properties and makes it of interest where conventional semiconductors face limitations in specific thermal or catalytic environments.
