Ta1 Cu3 Se4
metal· Ta1 Cu3 Se4
Ta₁Cu₃Se₄ is a ternary metal selenide compound combining tantalum, copper, and selenium in a fixed stoichiometric ratio. This material belongs to the family of transition metal chalcogenides and is primarily of research interest rather than established industrial production. The compound is investigated for potential applications in thermoelectric devices, optoelectronic components, and energy conversion systems, where mixed-metal selenides show promise for tunable electronic and thermal properties; however, it remains largely experimental with limited commercial deployment compared to more mature semiconductor alternatives.
