· JVASP-4525· Yb2Se3

Yb₂Se₃ is a rare-earth selenide ceramic compound belonging to the lanthanide chalcogenide family, characterized by ionic bonding between ytterbium and selenium atoms. This material is primarily studied in research contexts for optoelectronic and thermoelectric applications, where its bandgap and phonon properties offer potential advantages in mid-infrared emission, infrared detectors, and solid-state cooling devices; it remains largely experimental rather than widely deployed in production.
