About ZnCdSe2
ZnCdSe2 is a ternary semiconductor composed of zinc, cadmium, and selenium. Its electronic character suggests it belongs to a family of materials often investigated for their tunable optoelectronic properties, bridging the gap between binary chalcogenide systems.
As a near-hull phase, this compound is considered a viable candidate for experimental synthesis. The existence of multiple reported structures indicates a rich structural landscape that warrants further investigation for potential use in semiconductor device development.
Key Properties
Cross-validated computational properties for ZnCdSe2, 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.
