SbTeI is a ternary chalcohalide semiconductor compound combining antimony, tellurium, and iodine elements. This material belongs to the family of layered semiconductors and is primarily investigated in research contexts for optoelectronic and photovoltaic applications, where its tunable bandgap and anisotropic crystal structure offer potential advantages over binary semiconductors. While not yet widely deployed in mainstream industrial production, SbTeI and related compounds are of interest for next-generation solar cells, infrared detectors, and thermoelectric devices where conventional materials face efficiency or cost limitations.
