TmCuSe2
metal· TmCuSe2
TmCuSe2 is an intermetallic compound combining thulium, copper, and selenium, belonging to the family of ternary chalcogenides. This is a research-phase material rather than an established industrial compound; such materials are investigated primarily for their potential thermoelectric, magnetic, or optoelectronic properties that emerge from the specific arrangement of rare-earth and transition-metal elements. The compound's notable stiffness and moderate density suggest potential applications in specialized thermal management or electronic device contexts where unconventional material properties are required.
