CaEu3
CaEu3 is a metallic binary intermetallic compound composed of calcium and europium that is considered a viable candidate for experimental synthesis.
About CaEu3
CaEu3 is a metallic intermetallic compound formed from the combination of calcium and europium. As a material with no band gap, it exhibits characteristic metallic electronic behavior that makes it a subject of interest for fundamental studies in condensed matter physics. Its structural configuration and electronic properties are defined by the interplay between these two alkaline earth and lanthanide elements. The compound is considered near-hull, suggesting it is thermodynamically stable enough to be a viable candidate for experimental synthesis. With multiple reported structures across various databases, it represents a well-documented phase that provides researchers with a clear roadmap for further investigation into its physical characteristics and potential utility.
Key Properties
Cross-validated computational properties for CaEu3, 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.
