· JVASP-140240· Tm2Te3

Tm2Te3 is a rare-earth telluride ceramic compound combining thulium (a lanthanide) with tellurium in a 2:3 stoichiometry. This material is primarily of research interest rather than established industrial use, studied for its potential thermoelectric and optoelectronic properties within the broader family of rare-earth chalcogenides. Applications remain experimental but focus on high-temperature energy conversion and narrow-bandgap semiconductor devices where the unique electronic structure of thulium-tellurium systems offers advantages over conventional alternatives.
