Er3Te4
semiconductor· Er3Te4
Er₃Te₄ is a rare-earth telluride compound composed of erbium and tellurium, belonging to the class of chalcogenide semiconductors. This material is primarily of research interest for thermoelectric and optoelectronic applications, where rare-earth tellurides show promise for mid-infrared photonics and solid-state cooling due to their bandgap characteristics and phonon-scattering behavior. While not yet widely deployed in mainstream industrial applications, Er₃Te₄ represents an emerging material within the broader rare-earth chalcogenide family being explored for next-generation energy conversion and quantum/infrared sensing systems.
