· JVASP-91819· NaGaTe2

NaGaTe2 is a ternary ceramic compound composed of sodium, gallium, and tellurium, belonging to the class of chalcogenide ceramics. This material is primarily of research interest for optoelectronic and photonic applications, where its semiconducting properties and potential for infrared transmission make it relevant to the compound semiconductor family. While not yet widely deployed in high-volume industrial production, NaGaTe2 and related sodium-containing chalcogenides are investigated for infrared optical windows, nonlinear optical devices, and potential thermoelectric applications where the combination of ionic and covalent bonding offers tunable electronic properties.
