As4 Ta2

As₄Ta₂ is an experimental intermetallic compound combining arsenic and tantalum in a semiconducting phase, investigated primarily in research contexts for its electronic and structural properties. This material belongs to the family of transition metal arsenides, which are studied for potential applications in thermoelectric devices, optoelectronics, and high-temperature semiconducting applications where conventional silicon or gallium-based semiconductors reach performance limits. While not yet established in mainstream industrial production, materials in this compound family are of interest to researchers developing next-generation electronic materials that can operate in demanding thermal or chemical environments.
