· JVASP-78282· LaTe

LaTe is a ceramic compound composed of lanthanum and tellurium, belonging to the rare-earth chalcogenide family of materials. This material is primarily of research interest for optoelectronic and thermoelectric applications, where its electronic properties and thermal characteristics make it relevant for solid-state device development. LaTe represents an emerging class of materials being investigated for specialized high-temperature electronics and photonic applications where conventional semiconductors or ceramics may be insufficient.
