Na2 Sb2 Se4
semiconductor· Na2 Sb2 Se4
Na₂Sb₂Se₄ is a layered semiconductor compound belonging to the chalcogenide family, combining sodium, antimony, and selenium in a anionic framework structure. This material is primarily investigated in research contexts for thermoelectric and optoelectronic applications, where its layered crystal structure and tunable bandgap offer potential advantages in energy conversion and light absorption compared to conventional semiconductors. The sodium-antimony-selenide system is of particular interest for solid-state devices and thin-film technologies where the weak van der Waals interlayer interactions enable mechanical exfoliation and integration into heterostructures.
