Au2GaMg
Au2GaMg is a stable, semimetallic ternary intermetallic compound composed of gold, gallium, and magnesium.
About Au2GaMg
Au2GaMg is a distinct intermetallic compound composed of gold, gallium, and magnesium. As a thermodynamically stable phase located on the convex hull, it represents a robust structural arrangement of these metallic elements.
Characterized as a near-zero-gap semimetallic material, its electronic structure places it in a unique regime between traditional metals and semiconductors. This electronic profile makes it an intriguing subject for fundamental studies into the behavior of complex ternary alloys.
Key Properties
Cross-validated computational properties for Au2GaMg, aggregated across 3 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 Au2GaMg. 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.
