· Cs2Ta2P2Se12

Cs2Ta2P2Se12 is a layered chalcogenide semiconductor composed of cesium, tantalum, phosphorus, and selenium. This is a research-phase compound within the family of metal phosphorus chalcogenides, which are being explored for their tunable electronic and optical properties arising from their layered crystal structure. While not yet in widespread industrial production, materials in this family are of significant interest for next-generation optoelectronic and quantum applications due to their potential for direct bandgaps, strong light-matter interactions, and two-dimensional behavior when exfoliated.
