Its position on the convex hull confirms that it is a thermodynamically stable phase under standard conditions. The compound has been documented across multiple structural databases, reflecting its well-defined nature within its chemical family. Its stability and insulating behavior suggest potential utility in specialized optical or electronic applications where wide-gap materials are required.
Key Properties
Cross-validated computational properties for CdCl3K, 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.
