· JVASP-10724· KNdTe4

KNdTe4 is a rare-earth telluride ceramic compound containing potassium, neodymium, and tellurium. This is a research-phase material studied primarily for its potential in thermoelectric and optoelectronic applications, where rare-earth tellurides are investigated for energy conversion and light emission properties. The material represents an experimental composition within the broader class of rare-earth chalcogenides, which continue to attract academic and industrial interest for advanced electronic and thermal management systems where conventional ceramics fall short.
