Au1Li2Pt1
Au1Li2Pt1 is a metastable, semimetallic ternary alloy composed of gold, lithium, and platinum, studied primarily for its complex structural properties.
About Au1Li2Pt1
Au1Li2Pt1 is a complex ternary alloy categorized within the platinum-group metal systems. As a semimetallic compound, it exhibits electronic properties that bridge the gap between conductors and insulators, making it a subject of interest for those studying fundamental electronic behavior in metallic alloys.
While this compound is noted for having numerous reported structural variations, its position above the thermodynamic hull suggests it is a metastable phase. This metastability is a critical factor for researchers investigating the synthesis and potential catalytic utility of complex lithium-bearing platinum alloys.
Key Properties
Cross-validated computational properties for Au1Li2Pt1, 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.
