NaCo2O3
NaCo2O3 is a metastable, semiconducting layered oxide containing sodium, cobalt, and oxygen used in materials science research.
About NaCo2O3
NaCo2O3 is a semiconducting member of the layered sodium transition-metal oxide family. Its structural arrangement reflects the complex chemistry inherent to cobalt-based systems, where the arrangement of alkali ions and transition metal layers dictates its physical properties.
As a metastable phase, this compound is of significant interest to materials scientists exploring non-equilibrium synthesis pathways. Its unique electronic character makes it a candidate for fundamental studies in energy storage and electrochemical systems where structural stability and ion transport are critical.
Key Properties
Cross-validated computational properties for NaCo2O3, 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.
