· Si6 As2

Si₆As₂ is an experimental semiconductor compound belonging to the silicon-arsenic family, representing a non-stoichiometric phase that bridges traditional III-V semiconductors and group IV materials. This material remains primarily in research and development stages, with potential applications in high-frequency electronics and optoelectronics where the unique band structure of silicon-arsenic compounds could enable performance advantages over conventional materials, though practical device implementation is limited by synthesis complexity and material stability challenges.
