Na12 Co2 Se8
semiconductor· Na12 Co2 Se8
Na12Co2Se8 is a ternary metal selenide compound belonging to the class of layered semiconductor materials, combining sodium, cobalt, and selenium in a structured crystal lattice. This material is primarily of research interest for thermoelectric and energy conversion applications, where its layered structure and mixed-metal composition offer potential for tuning electronic properties and phonon scattering. While not yet widely deployed in commercial products, materials in this family are investigated as alternatives to traditional thermoelectrics and for potential use in solid-state energy harvesting devices where chemical stability and synthetic tunability are valued over conventional chalcogenides.
