Er(CuTe)3
semiconductor· 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.
