· K6Nb2.97Ta1.03S25

K6Nb2.97Ta1.03S25 is a potassium-niobium-tantalum sulfide compound belonging to the Chevrel phase family of layered transition metal chalcogenides. This material is primarily of research and developmental interest for applications requiring superconducting or semiconducting properties at low temperatures, as the Chevrel phase family is known for exhibiting superconductivity and tunable electronic behavior through compositional variation. The substitution of tantalum for niobium in this sulfide framework allows fine-tuning of electronic structure and is notably studied for low-dimensional charge transport and potential thermoelectric or topological properties.
