HoAgSe2
metal· JVASP-11074· HoAgSe2
HoAgSe2 is an intermetallic compound combining holmium, silver, and selenium, belonging to the rare-earth metal chalcogenide family. This is a research material studied primarily for its thermoelectric and magnetic properties rather than established commercial use. Interest in this compound stems from its potential in advanced energy conversion and solid-state cooling applications, where rare-earth chalcogenides are explored as alternatives to conventional thermoelectric materials, though practical engineering adoption remains limited to laboratory and prototype-scale investigation.
