· Ni3 Bi2 S2

Ni₃Bi₂S₂ is a ternary chalcogenide semiconductor compound combining nickel, bismuth, and sulfur. This material belongs to the family of metal chalcogenides and is primarily of research interest rather than established in high-volume industrial production. The compound is investigated for potential applications in thermoelectric energy conversion, optoelectronic devices, and solid-state electronics where its layered crystal structure and band gap characteristics may offer advantages in heat-to-electricity conversion or light-based sensing.
