Zn5SeS4

Zn5SeS4 is a mixed-anion zinc chalcogenide ceramic compound combining selenium and sulfur in a single crystal lattice, placing it in the family of semiconducting ceramics used for optoelectronic and photonic applications. This material is primarily of research interest rather than widespread industrial production, with potential applications in photodetectors, solar cells, and nonlinear optical devices where the mixed chalcogenide composition can be engineered to tune bandgap and optical response. Its appeal lies in the ability to customize electronic properties through compositional variation while maintaining the mechanical stability of a ceramic matrix—a strategy increasingly explored for next-generation semiconductors where conventional materials reach performance limits.
