Au2Cd1Ti1
Au2Cd1Ti1 is a semiconducting ternary compound consisting of gold, cadmium, and titanium that is currently studied for its unique structural and electronic properties.
About Au2Cd1Ti1
Au2Cd1Ti1 is a complex ternary compound composed of gold, cadmium, and titanium. As a semiconducting material, it represents a unique intersection of noble metal, post-transition metal, and transition metal chemistry, offering a distinct electronic profile for research into advanced solid-state systems.
While this compound has been identified across multiple structural reports, it is characterized as being thermodynamically above the hull. This suggests that while it can exist in specific configurations, it may require precise synthesis conditions to stabilize compared to more robust, ground-state intermetallic phases.
Key Properties
Cross-validated computational properties for Au2Cd1Ti1, 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.
