TbAgSe2
metal· JVASP-37406· TbAgSe2
TbAgSe2 is an intermetallic compound combining terbium, silver, and selenium, belonging to the family of rare-earth based ternary semiconductors and thermoelectric materials. This is primarily a research material rather than an established industrial commodity, of interest for its potential in thermoelectric energy conversion and solid-state cooling applications where the combination of rare-earth and chalcogenide chemistry may offer favorable electronic and phonon transport properties. Engineers and researchers investigate such compounds for next-generation thermal management systems and waste-heat recovery devices where conventional materials reach performance limits.
