Na4 Zn6 Se8

Na₄Zn₆Se₈ is a quaternary semiconductor compound combining sodium, zinc, and selenium in a fixed stoichiometric ratio, belonging to the family of mixed-metal chalcogenides. This material is primarily of research interest for optoelectronic and photovoltaic applications, where its bandgap and crystal structure make it a candidate for thin-film solar cells, light-emitting devices, and photodetectors—though it remains largely in the development phase compared to more mature semiconductors like CdTe or CIGS.
