· Cu3 Sb1

Cu₃Sb₁ is an intermetallic compound belonging to the copper-antimony system, classified as a semiconductor material. This binary phase is of primary interest in thermoelectric and optoelectronic research, where copper-antimony compositions are investigated for their electrical and thermal transport properties. Cu₃Sb₁ remains largely experimental; its practical deployment is limited, but the copper-antimony family shows potential for niche applications where semiconductor behavior combined with metallic conductivity is advantageous.
