· Tl1 Co1 As2

TlCoAs₂ is a ternary intermetallic semiconductor compound combining thallium, cobalt, and arsenic in a 1:1:2 stoichiometric ratio. This is primarily a research material studied for its electronic and thermoelectric properties within the broader family of transition metal pnictide semiconductors. While not yet widely deployed in commercial applications, materials in this class are of interest for potential thermoelectric energy conversion, optoelectronic devices, and fundamental solid-state physics investigations, particularly as alternatives to more conventional III-V 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.
