· JVASP-100784· YbHo2Se4

YbHo₂Se₄ is a rare-earth selenide ceramic compound combining ytterbium and holmium with selenium, belonging to the family of lanthanide chalcogenides. This is a research-phase material studied primarily for its potential in thermal management, optical, and magnetothermoelectric applications where rare-earth ion interactions enable unique electronic and thermal properties. While not yet widely deployed in production engineering, compounds in this chemical family are of interest for next-generation thermoelectric devices, magnetic refrigeration systems, and specialized photonic or sensing applications where the combination of rare-earth elements offers advantages over conventional ceramics.
