· Cs3Nb9(TeO8)4

Cs₃Nb₉(TeO₈)₄ is a complex mixed-metal oxide semiconductor composed of cesium, niobium, and tellurium in a layered perovskite-related structure. This is a research-phase compound studied primarily for its potential in photocatalytic and optoelectronic applications, belonging to the family of mixed-metal tellurates that show promise for light-driven processes and solid-state electronics. Engineers would consider this material in emerging technologies where novel bandgap engineering and crystal structure control are needed to achieve performance unavailable from conventional oxide semiconductors.
