· Er(CuTe)3

Er(CuTe)₃ is a ternary intermetallic semiconductor compound combining erbium, copper, and tellurium in a 1:3:3 stoichiometry. This is a research-phase material studied primarily in the context of narrow-bandgap semiconductors and thermoelectric applications, rather than an established commercial product. The compound belongs to the family of rare-earth chalcogenides and is of interest for potential use in mid-infrared optoelectronics, solid-state cooling, and high-temperature electronic devices where its electronic and thermal transport properties may offer advantages over conventional 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.
