GaPt is a thermodynamically stable, metallic alloy composed of gallium and platinum that is primarily utilized in catalytic research.
About GaPt
GaPt is a metallic platinum-group alloy that occupies a stable position on the thermodynamic convex hull. Its robust structural integrity and electronic properties make it a subject of significant interest in materials science, particularly for applications requiring durable catalytic surfaces.
With a high degree of structural data available across multiple databases, this compound serves as a well-characterized model for understanding the interactions between gallium and platinum. Its metallic nature facilitates efficient electron transport, which is a critical requirement for advanced catalytic processes.
Key Properties
Cross-validated computational properties for GaPt, 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 GaPt. Tight agreement means computed properties can be trusted without re-running calculations.
