About Ge1In1Li2
Ge1In1Li2 is a ternary compound composed of germanium, indium, and lithium. As a semiconducting material, it represents a complex arrangement of group thirteen, fourteen, and alkali metal elements that offers a unique electronic profile for research into specialized solid-state systems.
While this compound exhibits a variety of reported structural configurations, it is characterized by a thermodynamic state that sits above the hull. This suggests that the material may be metastable or require specific synthesis conditions to stabilize, making it a subject of interest for computational materials discovery.
Key Properties
Cross-validated computational properties for Ge1In1Li2, 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.
