· S1 Te2 Bi2

S₁Te₂Bi₂ is a ternary chalcogenide ceramic compound combining sulfur, tellurium, and bismuth—elements commonly studied in thermoelectric and optoelectronic material research. This composition falls within the family of bismuth telluride-based semiconductors and is primarily of research interest rather than established production use, with potential applications in thermoelectric devices, infrared optics, or phase-change memory systems where chalcogenide glasses and crystalline phases show promise.
