· CsTa3(SeO6)2

CsTa3(SeO6)2 is an inorganic compound semiconductor composed of cesium, tantalum, and selenate groups, belonging to the family of complex metal selenates. This is a research-phase material studied for its potential in photonic and electronic applications due to its layered crystal structure and semiconducting behavior. Interest in this compound stems from the tunable electronic properties of tantalum-based ceramics and the optical characteristics of selenate coordination chemistry, positioning it as a candidate for emerging photovoltaic, nonlinear optical, or solid-state device research rather than established industrial production.
