Ba2Cd1Ge1
Ba2Cd1Ge1 is a semimetallic ternary compound composed of barium, cadmium, and germanium that exhibits significant structural diversity.
About Ba2Cd1Ge1
Ba2Cd1Ge1 is a complex ternary intermetallic compound composed of barium, cadmium, and germanium. Its electronic structure is characterized as a near-zero-gap semimetal, placing it in a unique position between metallic conductors and semiconducting materials.
As a material that sits above the thermodynamic hull, this compound is considered metastable, which presents interesting challenges and opportunities for synthesis and structural characterization. With numerous reported structural variations, it remains a subject of interest for fundamental solid-state chemistry research.
Key Properties
Cross-validated computational properties for Ba2Cd1Ge1, 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.
