Cu2 In1 Er1
semiconductor· Cu2 In1 Er1
Cu₂InEr is an experimental ternary semiconductor compound combining copper, indium, and erbium. This material belongs to the broader family of multinary semiconductors being explored for optoelectronic and photonic applications, where the rare-earth erbium dopant is of particular interest for telecommunications wavelengths (1.55 μm). While not yet commercially established, compounds in this chemical family are investigated for potential use in integrated photonics, laser materials, and specialized light-emitting or light-detecting devices where rare-earth incorporation can enhance optical performance.
