· JVASP-79800· NdTlSe2

NdTlSe2 is a ternary ceramic compound combining neodymium, thallium, and selenium, belonging to the family of rare-earth chalcogenides. This is a research-phase material studied primarily for its electronic and optical properties rather than as an established engineering material; compounds in this family are investigated for potential applications in thermoelectric devices, semiconductor research, and quantum materials where rare-earth elements provide magnetic or electronic functionality.
