· Tb2 Cu2 As4

Tb₂Cu₂As₄ is a ternary intermetallic semiconductor compound combining terbium (a rare earth element), copper, and arsenic. This is a research-phase material studied primarily for its electronic and magnetic properties rather than established in widespread industrial production. The compound belongs to the family of rare-earth pnictide semiconductors, which are of interest for investigating quantum phenomena, magnetotransport effects, and potential applications in next-generation electronic or spintronic devices where the magnetic ordering of terbium and the semiconducting behavior of the arsenic framework could be exploited.
