Ag1Ba2Cd1
Ag1Ba2Cd1 is a semiconducting intermetallic compound containing silver, barium, and cadmium.
About Ag1Ba2Cd1
Ag1Ba2Cd1 is a complex intermetallic compound composed of silver, barium, and cadmium. As a semiconducting material, it exhibits distinct electronic characteristics that differentiate it from typical metallic alloys, making it a subject of interest for fundamental solid-state research.
While this phase is characterized by a high number of reported structures, its position above the thermodynamic hull suggests it may be metastable under standard conditions. Its unique elemental combination invites further investigation into the synthesis and stability of ternary silver-barium-cadmium systems.
Key Properties
Cross-validated computational properties for Ag1Ba2Cd1, 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.
StabilityA plain-language summary of the best reported energy-above-hull result. It reflects whether the lowest-energy structure is on, near, or far from the stability hull.
StructuresCount of reported calculated crystal structures for this formula, including alternate polymorphs, source databases, and observed space groups.
