CoPb3
CoPb3 is a metallic cobalt-lead intermetallic compound that exists as a metastable phase.
About CoPb3
CoPb3 is a metallic intermetallic compound composed of cobalt and lead. As a metallic system, it exhibits characteristic electronic behavior typical of transition metal-heavy metal alloys, reflecting the complex bonding interactions between the d-orbitals of cobalt and the p-orbitals of lead.
This material is recognized as being thermodynamically metastable, placing it above the convex hull in energy landscapes. Despite its instability, it has been the subject of significant structural investigation across multiple databases, highlighting interest in the diverse atomic arrangements possible within this binary chemical space.
Key Properties
Cross-validated computational properties for CoPb3, aggregated across 5 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.
