· JVASP-34995· LuSe2

LuSe₂ is a lutetium diselenide ceramic compound belonging to the rare-earth chalcogenide family, characterized by metallic bonding between lutetium and selenium atoms in a layered crystal structure. This material is primarily of research interest for semiconductor and optoelectronic applications, particularly in high-temperature thermoelectric devices and infrared sensing systems where rare-earth chalcogenides offer tunable electronic properties and thermal stability beyond conventional semiconductors. Its selection would be driven by specialized requirements in extreme-environment electronics or photonic systems where lutetium's unique electron configuration and selenium's semiconducting behavior combine to enable performance unavailable from more common ceramic alternatives.
