About Ge1La2Li1
Ge1La2Li1 is a ternary intermetallic compound composed of germanium, lanthanum, and lithium. It exhibits a near-zero-gap electronic character, placing it in the category of semimetallic materials that often demonstrate unique transport properties due to their specific band structure configurations. The material is categorized as being above the thermodynamic hull, suggesting it is a metastable phase. Its structural complexity is highlighted by a significant number of reported configurations across material databases, reflecting the diverse ways these elements can arrange themselves at the atomic scale.
Key Properties
Cross-validated computational properties for Ge1La2Li1, 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.
