KNbSe2 is a ternary metal selenide compound combining potassium, niobium, and selenium in a layered crystal structure. This material belongs to the family of transition metal chalcogenides and is primarily of research interest for its electronic and thermal properties rather than established commercial production. Potential applications include thermoelectric devices, solid-state batteries, and optoelectronic components, where layered metal selenides are being investigated as alternatives to conventional semiconductors and ionic conductors due to their tunable band structure and anisotropic properties.
