· Zn2 Sn2 Sb4

Zn₂Sn₂Sb₄ is a quaternary semiconductor compound belonging to the family of zinc-tin-antimony materials, which are being investigated as potential alternatives to traditional lead-based thermoelectric and optoelectronic semiconductors. This material is primarily of research interest for its potential in thermoelectric energy conversion and mid-infrared optoelectronic applications, where its layered crystal structure and band gap characteristics may enable efficient thermal-to-electrical conversion or infrared detection without the toxicity concerns of lead-containing competitors.
