· Be2 Si2 As4

Be₂Si₂As₄ is a quaternary semiconductor compound combining beryllium, silicon, and arsenic elements in a layered crystal structure. This material belongs to the family of III-V and II-VI semiconductor compounds and is primarily of research interest rather than established commercial production. The compound is investigated for potential optoelectronic and high-frequency applications due to its wide bandgap and thermal stability, though its practical use remains limited compared to more mature semiconductors like GaAs or GaN.
