· Na4 Cu2 As2

Na₄Cu₂As₂ is an intermetallic semiconductor compound containing sodium, copper, and arsenic elements, representing a quaternary phase in the Cu-As-Na system. This material is primarily of research and exploratory interest rather than established industrial production, as it belongs to a family of metallic arsenides being investigated for potential thermoelectric, optoelectronic, and solid-state electronic applications where mixed-valence metal behavior and semiconducting properties are beneficial.
