· JVASP-37134· NdTlTe2

NdTlTe2 is a ternary ceramic compound combining neodymium, thallium, and tellurium—a rare earth telluride belonging to the broader family of exotic ceramic materials with layered or complex crystal structures. This is primarily a research-phase material studied for its potential in thermoelectric and optoelectronic applications, where the combination of rare earth and chalcogenide elements can yield unusual electronic and thermal transport properties. While not yet established in mainstream industrial production, compounds in this family are of interest to materials researchers exploring next-generation energy conversion and solid-state device technologies where unconventional carrier behavior or strong phonon-electron coupling may be exploited.
