About Li7CuO4
Li7CuO4 is a lithium-rich oxide that exhibits semiconducting electronic behavior. As a metastable phase, it represents a complex arrangement of lithium, copper, and oxygen atoms that offers intriguing possibilities for materials research in solid-state chemistry.
Its significance lies in its specific compositional makeup, which distinguishes it from more common lithium-based oxides. Researchers study this compound to better understand the stability limits and structural variations possible within lithium-rich oxide systems.
Key Properties
Cross-validated computational properties for Li7CuO4, 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.
