LaSe2

LaSe₂ is a rare-earth selenide ceramic compound combining lanthanum with selenium, belonging to the family of lanthanide chalcogenides. This material is primarily of research interest for optoelectronic and thermoelectric applications, where its semiconducting properties and thermal characteristics are investigated for potential use in infrared detectors, thermal imaging systems, and solid-state energy conversion devices. While not yet widely deployed in mainstream engineering applications, lanthanide selenides like LaSe₂ represent an emerging class of functional ceramics with potential advantages in high-temperature stability and radiation hardness compared to conventional semiconductors.
