Ba2Ge1Hg1
Ba2Ge1Hg1 is a semiconducting ternary intermetallic compound containing barium, germanium, and mercury that is primarily studied for its structural properties.
About Ba2Ge1Hg1
Ba2Ge1Hg1 is a complex intermetallic compound composed of barium, germanium, and mercury. As a semiconducting material, it represents a unique intersection of alkaline earth metal, metalloid, and transition metal chemistry, offering a distinct electronic profile for fundamental materials study.
While this compound has been identified in structural databases, its thermodynamic profile suggests it exists in a metastable state above the hull. This indicates that its synthesis and long-term stability are highly sensitive to processing conditions, making it a subject of interest for researchers exploring complex phase spaces.
Key Properties
Cross-validated computational properties for Ba2Ge1Hg1, 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.
