About Cu2Zr
Cu2Zr is a metastable intermetallic phase composed of copper and zirconium. Its electronic character is defined as near-zero-gap, placing it in the category of semimetallic materials that exhibit unique conductive behaviors compared to traditional insulators or metals.
Due to its metastable nature, this compound is a subject of significant interest in phase-stability studies and materials design. It has been documented across multiple structural configurations, highlighting its complexity and the diverse ways copper and zirconium atoms can arrange themselves in solid-state systems.
Key Properties
Cross-validated computational properties for Cu2Zr, aggregated across 4 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.
