· JVASP-10977· TmCuS2

TmCuS2 is a ternary chalcogenide compound combining thulium, copper, and sulfur, representing an emerging class of materials in solid-state chemistry research rather than established engineering practice. This material belongs to the family of metal sulfides and is primarily of interest in materials research for potential applications in thermoelectric devices, photovoltaic systems, and solid-state electronics where mixed-metal chalcogenides show promise for tunable electronic and thermal properties. While not yet widely deployed in mainstream engineering, compounds of this type are investigated as alternatives to conventional semiconductors due to their potential for low thermal conductivity and adjustable band gap characteristics.
