RbNdSe2

RbNdSe₂ is a rare-earth selenide ceramic compound combining rubidium, neodymium, and selenium in a layered crystal structure. This is a research-phase material studied primarily for its electronic and optical properties rather than structural applications; it belongs to the family of rare-earth chalcogenides investigated for potential use in solid-state electronics, photonics, and thermoelectric devices. The material's combination of rare-earth dopants and semiconductor-like character makes it of interest in advanced functional ceramics, though it remains largely confined to laboratory settings and has not achieved widespread industrial adoption.
