· Yb2 As1 Au1

Yb₂As₁Au₁ is an intermetallic semiconductor compound combining ytterbium, arsenic, and gold in a fixed stoichiometric ratio. This is primarily a research-phase material studied for its electronic and thermoelectric properties rather than an established commercial product. The material belongs to the family of rare-earth intermetallics, where the unique electronic structure arising from ytterbium's f-electron configuration combined with arsenic and gold creates potential for specialized semiconductor applications in high-performance electronics and energy conversion devices.
