BeCu
BeCu is a metallic intermetallic compound formed from beryllium and copper that shows promise for experimental synthesis.
About BeCu
BeCu is a metallic intermetallic compound composed of beryllium and copper. Its electronic structure is characterized by a lack of a band gap, identifying it as a metallic conductor typical of binary alloys formed between these elements.
This material is considered near-hull in terms of thermodynamic stability, suggesting that it is a viable candidate for experimental synthesis. With a significant number of reported structures across various databases, it represents an interesting subject for researchers investigating the complex phase space of beryllium-based alloys.
Key Properties
Cross-validated computational properties for BeCu, 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.
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.
StructuresCount of reported calculated crystal structures for this formula, including alternate polymorphs, source databases, and observed space groups.
Cross-Source DFT Agreement
How well independent DFT databases agree on the thermodynamics of BeCu. Tight agreement means computed properties can be trusted without re-running calculations.
Agreement ScoreA normalized confidence score summarizing how closely independent DFT databases agree. Higher scores mean tighter cross-source agreement.
