· Ta1 Cu3 S4

Ta1Cu3S4 is a ternary sulfide semiconductor compound combining tantalum, copper, and sulfur in a fixed stoichiometric ratio. This material belongs to the family of metal chalcogenides and exists primarily in the research and development phase, investigated for potential optoelectronic and photovoltaic applications where its bandgap and electronic structure may offer advantages in light absorption or charge transport compared to conventional binary sulfides. While not yet established in volume production, ternary sulfides like this compound are explored by materials researchers as candidates for thin-film solar cells, photoelectrochemical devices, and solid-state electronics where the combination of different metal cations can tune material properties beyond what binary or simpler systems provide.

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.
