· JVASP-102320· Tm2TeS2

Tm2TeS2 is a ternary ceramic compound containing thulium, tellurium, and sulfur, belonging to the mixed-chalcogenide ceramic family. This is a research-phase material studied for its electronic and thermal properties rather than a widely commercialized engineering ceramic. The material shows potential in optoelectronic devices, solid-state thermal management, and semiconductor applications where rare-earth chalcogenide compounds are explored for their unique bandgap characteristics and phonon behavior.
