About Ag2Cd1In1
Ag2Cd1In1 is a ternary intermetallic compound composed of silver, cadmium, and indium. It exhibits a semimetallic electronic character, placing it in a regime where conduction properties are highly sensitive to its specific atomic arrangement. The material is characterized by a thermodynamic state that sits above the hull, suggesting it is a metastable phase. Its structural complexity is highlighted by a significant number of reported configurations across crystalline databases, making it a subject of interest for fundamental studies in phase stability.
Key Properties
Cross-validated computational properties for Ag2Cd1In1, 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.
