· JVASP-37114· RbSmTe2

RbSmTe₂ is an intermetallic ceramic compound combining rubidium, samarium, and tellurium, belonging to the rare-earth telluride family of materials. This is primarily a research-phase compound studied for its electronic and thermal properties rather than an established industrial material. The rubidium-rare-earth telluride family is of interest in thermoelectric, optoelectronic, and solid-state physics applications where the combination of rare-earth elements and heavy chalcogens can produce unusual band structures and phonon behavior.
