· S3 As1 Tl3

S₃As₁Tl₃ is a ternary semiconductor compound combining sulfur, arsenic, and thallium elements. This is a research-phase material studied for its semiconducting properties within the sulfide-arsenide-halide compound family, rather than an established commercial semiconductor. Interest in this composition centers on potential applications in infrared optics and specialized solid-state electronics where the combined constituent elements may offer unique band gap characteristics or optical response properties unavailable in binary or more conventional ternary semiconductors.

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.
