Co4 As4

Co₄As₄ is a cobalt arsenide semiconductor compound belonging to the transition metal pnictide family, characterized by a stoichiometric 1:1 cobalt-to-arsenic ratio. This material is primarily of research and exploratory interest, investigated for its potential in thermoelectric applications, magnetism studies, and next-generation semiconductor devices due to the electronic properties arising from cobalt-arsenic interactions. While not yet widely commercialized, cobalt arsenides represent a promising class of materials for high-temperature thermoelectric conversion and spintronic applications where the combination of metallic and semiconducting character offers advantages over conventional silicon or III-V semiconductors.
