Cu4Bi5S10

Cu4Bi5S10 is a quaternary sulfide compound belonging to the metal sulfide family, combining copper and bismuth with sulfur in a complex stoichiometric ratio. This material is primarily of research interest for thermoelectric and semiconductor applications, where bismuth-containing sulfides are explored for their potential to convert heat to electricity or vice versa. The compound represents an emerging material system that leverages bismuth's unique electronic properties alongside copper's conductivity, though it remains largely in the developmental stage rather than established industrial production.
