Zn1 Ga2 Se4

Zn₁Ga₂Se₄ is a ternary II-VI semiconductor compound combining zinc, gallium, and selenium in a defect tetrahedral crystal structure. This material is primarily of research interest for optoelectronic and photovoltaic applications, where its direct bandgap and tunable electronic properties position it as a candidate for solar cells, photodetectors, and light-emitting devices. While not yet widely commercialized compared to binary semiconductors like GaAs or CdSe, ternary chalcogenides like Zn₁Ga₂Se₄ offer design flexibility for bandgap engineering and potential advantages in radiation hardness and thermal stability for space and high-energy applications.
