· JVASP-15366· TlNi2Se2

TlNi2Se2 is an intermetallic compound combining thallium, nickel, and selenium in a layered crystal structure. This material remains primarily in the research phase, studied for its potential thermoelectric and electronic properties rather than established industrial applications. Interest centers on its possible use in next-generation energy conversion devices and quantum materials research, where the combination of heavy thallium atoms and transition metal-chalcogen bonding may yield favorable charge transport characteristics.
