Se2 Sb2 Te1
semiconductor· Se2 Sb2 Te1
Se₂Sb₂Te₁ is a quaternary chalcogenide semiconductor compound within the selenium-antimony-tellurium family, materials known for their tunable bandgap and phase-change properties. This composition sits in the research domain of advanced thermoelectric and phase-change memory materials, where the balance of Se, Sb, and Te elements is engineered to optimize thermal transport, electrical conductivity, and crystalline switching behavior. While not yet established as a mainstream commercial alloy, compounds in this family are investigated for applications requiring controlled electronic switching, thermal management, or energy conversion at modest temperatures.
