Tl1 Co1 As2
semiconductor· 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.
