About Na3CuO2
Na3CuO2 is a distinct inorganic compound composed of sodium, copper, and oxygen. As a thermodynamically stable phase located on the convex hull, it represents a robust configuration within its chemical system, drawing significant interest from researchers investigating complex oxide materials. Its semiconducting electronic character makes it a subject of study for potential applications in electronic and optoelectronic devices where specific charge transport properties are required. The material is characterized by a high degree of structural diversity, as evidenced by the numerous reported configurations documented across various materials databases. This structural richness suggests a complex energy landscape that allows for multiple atomic arrangements, providing a fertile ground for exploring structure-property relationships in copper-based oxides.
Key Properties
Cross-validated computational properties for Na3CuO2, aggregated across 3 databases.
Band GapEnergy needed to move an electron from the valence band to the conduction band. Lower or zero values tend to behave more metallic; larger gaps are more insulating or semiconducting.
Energy Above HullThermodynamic distance from the most stable set of competing phases. 0 eV/atom is on the convex hull; small positive values may still be experimentally accessible.
