· Er1 Tl1 Te2

Er1Tl1Te2 is an experimental ternary semiconductor compound combining erbium, thallium, and tellurium. This material belongs to the family of mixed-metal tellurides and represents a research-phase composition with potential applications in infrared optics and thermoelectric devices, where the rare-earth (erbium) and heavy-metal (thallium) constituents may enable specialized optical or thermal properties distinct from binary telluride semiconductors.

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.
