The compound has been extensively characterized across multiple databases, reflecting significant interest in its structural diversity and potential for specialized electronic applications. Its well-defined crystalline arrangements provide a stable platform for investigating the interplay between heavy alkaline earth metals and group fourteen elements.
Key Properties
Cross-validated computational properties for Sr2Ge, aggregated across 4 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.
