CdSr2Zn
CdSr2Zn is a semiconducting ternary intermetallic compound characterized by its metastable nature and structural complexity.
About CdSr2Zn
CdSr2Zn is a ternary intermetallic compound composed of cadmium, strontium, and zinc. As a semiconducting material, it represents a complex arrangement of elements that has been documented across multiple structural databases, reflecting its interest in solid-state chemistry research. Because this compound sits above the thermodynamic hull, it is considered metastable under standard conditions. Its existence in multiple reported structures highlights the intricate phase space of cadmium-strontium-zinc systems and the ongoing efforts to synthesize and characterize such specialized phases.
Key Properties
Cross-validated computational properties for CdSr2Zn, aggregated across 3 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.
