· K6Ta1.03Nb2.97S25

K6Ta1.03Nb2.97S25 is a layered transition metal sulfide compound containing potassium, tantalum, and niobium in a stoichiometric framework. This is a research-phase semiconductor material belonging to the family of dichalcogenides and related metal sulfides, studied for its electronic and photonic properties rather than established in high-volume industrial production. The combination of heavy transition metals (Ta, Nb) with sulfur creates a material of interest for energy conversion, photoelectrochemistry, and next-generation semiconductor device applications where band gap engineering and layered crystal structure offer advantages over conventional semiconductors.
