· Na1 Sc1 S2

Sodium scandium disulfide (NaScS₂) is an ionic semiconductor compound combining alkali metal, rare-earth transition metal, and chalcogen elements. This material belongs to the family of ternary sulfides and remains primarily in the research and development phase, with potential applications in solid-state ionic conductors, photovoltaic absorbers, and advanced semiconductor devices. Interest in this compound stems from the unique electronic and ionic properties that emerge from combining sodium's high mobility with scandium's transition-metal chemistry, offering a platform for exploring new mechanisms in energy conversion and storage materials.
