Cu2K2O4
Cu2K2O4 is a stable semiconducting ternary oxide composed of copper, potassium, and oxygen.
About Cu2K2O4
Cu2K2O4 is a distinct ternary oxide characterized by its semiconducting electronic nature. As a thermodynamically stable phase residing on the convex hull, it represents a robust structural arrangement of copper, potassium, and oxygen atoms.
Its existence across multiple reported structures highlights its significance in solid-state chemistry. This stability makes it a compelling subject for researchers investigating the interplay between transition metals and alkali metals in complex oxide frameworks.
Key Properties
Cross-validated computational properties for Cu2K2O4, 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.
