Ba1Cd1Hg2
Ba1Cd1Hg2 is a semimetallic, metastable ternary intermetallic compound containing barium, cadmium, and mercury.
About Ba1Cd1Hg2
Ba1Cd1Hg2 is a complex ternary intermetallic compound composed of barium, cadmium, and mercury. Its electronic structure exhibits semimetallic characteristics, placing it in a unique regime where traditional insulating or metallic behaviors are bridged by near-zero-gap features.
Due to its position above the thermodynamic hull, this material is considered metastable, which underscores the complexity of its synthesis and structural formation. Its prevalence in structural databases highlights its significance as a subject of study for researchers investigating the interplay of heavy elements in solid-state chemistry.
Key Properties
Cross-validated computational properties for Ba1Cd1Hg2, 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.
