GaMg
GaMg is a stable metallic intermetallic compound composed of gallium and magnesium.
About GaMg
GaMg is a metallic intermetallic compound formed from gallium and magnesium. As a thermodynamically stable phase located on the convex hull, it represents a robust structural arrangement of these two elements, reflecting a favorable energetic state that persists under standard conditions. Its metallic character suggests high electrical and thermal conductivity, which are characteristic of its constituent elements in this binary configuration. The compound is supported by a significant body of structural data, highlighting its importance in fundamental materials research. Its stability and predictable formation make it a subject of interest for understanding alloy behavior and phase development in binary metallic systems.
Key Properties
Cross-validated computational properties for GaMg, 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.
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 GaMg. 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.
