Cu2CO5
Cu2CO5 is a semimetallic copper-carbon-oxygen compound that exhibits metastable characteristics.
About Cu2CO5
Cu2CO5 is a copper-based compound characterized by its near-zero-gap electronic structure, placing it in the semimetallic regime. Its composition of copper, carbon, and oxygen suggests a complex coordination environment that is frequently investigated for its unique electronic properties.
Due to its position above the thermodynamic hull, this material is considered metastable under standard conditions. Its existence across multiple reported structures highlights the ongoing interest in characterizing its stability and potential pathways for synthesis.
Key Properties
Cross-validated computational properties for Cu2CO5, 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.
StabilityA plain-language summary of the best reported energy-above-hull result. It reflects whether the lowest-energy structure is on, near, or far from the stability hull.
