Ge2Li1Pt1
Ge2Li1Pt1 is a semiconducting intermetallic alloy composed of germanium, lithium, and platinum that is studied for its structural complexity.
About Ge2Li1Pt1
Ge2Li1Pt1 is a semiconducting intermetallic compound belonging to the broader family of platinum-group alloy catalysts. Its unique composition of germanium, lithium, and platinum positions it as a subject of interest for fundamental studies in solid-state chemistry and materials design.
While the compound is currently classified as thermodynamically unstable relative to its constituent phases, its structural diversity is evidenced by numerous reported configurations. This complexity makes it a compelling candidate for researchers investigating metastable phases in complex alloy systems.
Key Properties
Cross-validated computational properties for Ge2Li1Pt1, 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.

How It Compares
Within the platinum-group alloy catalysts class.
Unlike more stable, well-characterized members of the platinum-group alloy class such as GeRu or As2Pt, Ge2Li1Pt1 is distinguished by its position above the thermodynamic hull. While siblings like GeRu often exhibit robust stability, this compound represents a more challenging, metastable structural arrangement that requires specific synthesis conditions to isolate.
