Ta4 Bi4 O16
semiconductor· Ta4 Bi4 O16
Ta₄Bi₄O₁₆ is a mixed-metal oxide semiconductor combining tantalum and bismuth in a layered perovskite-related structure. This is primarily a research-phase material studied for photocatalytic and optoelectronic applications, where its bandgap and layered crystal structure make it a candidate for visible-light-driven processes and potential ferroelectric behavior.
