· JVASP-123686· NeSe2

NeSe2 is an experimental ceramic compound combining neon and selenium in a 1:2 stoichiometric ratio, representing a rare member of the noble gas chalcogenide family. This material exists primarily in research contexts, where it is studied for potential applications in wide-bandgap semiconductor devices, advanced optical components, and extreme-environment electronics due to the unique electronic properties imparted by noble gas bonding. While not yet commercialized, NeSe2 and related noble gas compounds are of interest to materials researchers exploring alternatives to conventional semiconductors for specialized high-performance or radiation-resistant applications.
