· Co1 Cu2 Sn1 S4

Co₁Cu₂Sn₁S₄ is a quaternary sulfide semiconductor compound combining cobalt, copper, tin, and sulfur in a mixed-metal chalcogenide structure. This material belongs to the family of multinary sulfides and represents an emerging research compound rather than an established commercial material; it is primarily of interest in photovoltaic and thermoelectric research where the combination of earth-abundant elements (copper, tin, sulfur) with transition metals offers potential for cost-effective semiconductor devices. The material's relevance lies in its potential as an alternative to conventional semiconductors in thin-film photovoltaics or as a candidate for solid-state thermoelectric applications, though maturity and scalability remain open research questions.

Export Control

RoHS, REACH, and Prop 65 statuses are validated against official substance lists (ECHA SVHC Candidate List, OEHHA Prop 65, RoHS Annex II). Other regulations are estimated from composition and material classification. All screening is a starting point for due diligence — always verify with your supplier before making compliance decisions.
