About Ga1In1Pd2
Ga1In1Pd2 is a specialized intermetallic compound within the platinum-group alloy catalyst class. Characterized by its semiconducting electronic nature, this material represents a complex arrangement of gallium, indium, and palladium atoms that has been documented across multiple structural configurations.
While its thermodynamic profile suggests it sits above the stability hull, the material remains a subject of interest in solid-state chemistry. Its unique composition allows researchers to investigate how mixing p-block elements with noble metals influences catalytic potential and electronic behavior in advanced material synthesis.
Key Properties
Cross-validated computational properties for Ga1In1Pd2, aggregated across 2 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.
