Ge1Li2Sr1
Ge1Li2Sr1 is a semiconducting ternary compound of germanium, lithium, and strontium that is currently considered thermodynamically unstable.
About Ge1Li2Sr1
Ge1Li2Sr1 is a ternary compound composed of germanium, lithium, and strontium. As a semiconducting material, it represents a specific combination of elements that has been explored within computational databases to understand its potential structural configurations.
While this material has been identified across multiple structural models, it is classified as being above the thermodynamic hull. This indicates that it is likely unstable under standard conditions, positioning it as a subject of interest for theoretical studies rather than immediate practical implementation.
Key Properties
Cross-validated computational properties for Ge1Li2Sr1, 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.
