GaRu
GaRu is a stable, metallic intermetallic alloy composed of gallium and ruthenium that is studied for its catalytic potential.
About GaRu
GaRu is a metallic intermetallic compound belonging to the platinum-group alloy catalyst family. Its position on the convex hull confirms its thermodynamic stability, making it a robust candidate for chemical processes requiring durable, high-performance metallic phases. The material is characterized by a high degree of structural complexity, supported by extensive data across multiple databases. Its metallic electronic character suggests high electrical conductivity, which is a critical feature for catalytic applications involving electron transfer. By leveraging the unique coordination environments provided by the gallium and ruthenium framework, this compound serves as a specialized building block in materials engineering. It is primarily investigated for its potential in heterogeneous catalysis, where the synergistic interaction between the transition metal and the post-transition metal element can tune surface reactivity.
Key Properties
Cross-validated computational properties for GaRu, 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.
