CdClO
CdClO is a metallic, thermodynamically unstable compound categorized within the family of transparent conducting oxides.
About CdClO
CdClO is an intriguing member of the transparent conducting oxide family, characterized by its metallic electronic nature. Despite its classification, the material exhibits thermodynamic instability, positioning it above the hull in terms of energy. Its complex structural landscape is evidenced by multiple reported configurations across various databases. Researchers study this compound to better understand the limits of conductivity and stability within metal-oxide systems. While it shares the chemical lineage of standard transparent conductors, its metallic behavior distinguishes it from the typical wide-gap insulators found in this class. Its presence in structural databases highlights its role as a subject of fundamental investigation into metastable phases.
Key Properties
Cross-validated computational properties for CdClO, aggregated across 5 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.
StructuresCount of reported calculated crystal structures for this formula, including alternate polymorphs, source databases, and observed space groups.
Cross-Source DFT Agreement
How well independent DFT databases agree on the thermodynamics of CdClO. Tight agreement means computed properties can be trusted without re-running calculations.
Agreement ScoreA normalized confidence score summarizing how closely independent DFT databases agree. Higher scores mean tighter cross-source agreement.
Hull SpreadDifference between the highest and lowest energy-above-hull values reported by comparable sources. Smaller spread means less thermodynamic disagreement.

How It Compares
Within the transparent conducting oxides class.
Unlike the highly stable and widely utilized ZnO, which serves as a benchmark for transparent conducting oxides, CdClO is characterized by its metallic electronic nature and thermodynamic instability. While siblings like BaSnO3 and ZnGa2O4 are valued for their robust performance in optoelectronic devices, CdClO remains a more theoretical subject of study due to its position above the hull.
