Gold · Aurum
Gold is a highly stable, noble metallic element widely recognized for its superior electrical conductivity and resistance to chemical degradation.
About Gold
Gold is a noble metallic element that holds a unique position in materials science due to its inherent thermodynamic stability and resistance to oxidation. As a pure element, it exhibits characteristic metallic bonding that facilitates excellent electrical and thermal transport properties.
Its structural versatility is evidenced by a vast array of reported configurations across major databases. This stability and reliability make it a foundational material in both fundamental research and high-performance industrial applications where long-term durability is essential.
Key Properties
Cross-validated computational properties for Gold, 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 Au. 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.
Hull SpreadDifference between the highest and lowest energy-above-hull values reported by comparable sources. Smaller spread means less thermodynamic disagreement.
Sources ComparedNumber and names of computational sources with comparable entries for this formula.
Space Group ConsensusWhether independent sources predict the same crystal symmetry for the lowest-energy structure.
