· Cu1 In1 Te4 Ta2

Cu₁In₁Te₄Ta₂ is an experimental quaternary semiconductor compound combining copper, indium, tellurium, and tantalum. This material belongs to the family of complex chalcogenide semiconductors and is primarily of research interest rather than established industrial production; it may be investigated for photovoltaic, thermoelectric, or optoelectronic applications where the layered chalcogenide structure and mixed-metal composition could enable tunable bandgap or enhanced charge transport properties.

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.
