· JVASP-123719· TmSe2

TmSe2 is a rare-earth chalcogenide ceramic compound composed of thulium and selenium, belonging to the family of layered dichalcogenides with potential semiconducting or semimetallic properties. This material is primarily investigated in research contexts for optoelectronic and thermoelectric applications, where its layered crystal structure and rare-earth composition offer opportunities for tuning electronic and phononic properties. Engineers considering TmSe2 should recognize it as an emerging functional ceramic rather than a mature production material, with potential advantages in niche high-performance applications where rare-earth chemical tunability provides benefits unavailable in conventional semiconductors or ceramics.
