Strontium telluride (SrTe) is an inorganic compound semiconductor belonging to the II-VI semiconductor family, characterized by a rock-salt crystal structure similar to other alkaline-earth chalcogenides. While primarily a research material rather than a high-volume industrial compound, SrTe is investigated for thermoelectric applications, infrared optics, and solid-state physics studies due to its wide bandgap and thermal properties; it represents a less-common alternative to more established II-VI semiconductors like CdTe or PbTe, with potential utility in niche applications requiring specific lattice parameters or thermal performance in moderate-temperature regimes.
