NaCu3O4
NaCu3O4 is a semimetallic copper-based oxide that is theoretically stable and of interest for its unique electronic properties.
About NaCu3O4
NaCu3O4 is a complex oxide featuring sodium and copper, characterized by a near-zero-gap electronic structure that places it in the semimetallic regime. Its proximity to the thermodynamic hull suggests that it is a viable candidate for experimental synthesis and structural characterization.
This material is significant due to its electronic properties, which bridge the gap between insulating oxides and metallic conductors. Given its presence in multiple structural databases, it represents a well-documented system for researchers investigating the interplay between copper-oxygen coordination and electronic transport.
Key Properties
Cross-validated computational properties for NaCu3O4, 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.
