· SrTe

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.

Export Control

RoHS, REACH, and Prop 65 statuses are validated against official substance lists (ECHA SVHC Candidate List, OEHHA Prop 65, RoHS Annex II). Other regulations are estimated from composition and material classification. All screening is a starting point for due diligence — always verify with your supplier before making compliance decisions.
