· JVASP-125001· Ar3As

Ar3As is an experimental ceramic compound in the rare-earth arsenide family, combining argon with arsenic in a 3:1 stoichiometry. This material exists primarily in research contexts for semiconductor and optoelectronic applications, where its electronic properties and crystal structure are of academic interest. While not yet commercialized at scale, arsenide ceramics in this composition range are investigated for potential use in high-frequency devices and specialized electronic applications where conventional semiconductors reach performance limits.
