CdCl2O
CdCl2O is a semiconducting oxychloride material that exists as a metastable phase within the transparent conducting oxide class.
About CdCl2O
CdCl2O is a semiconducting oxychloride that occupies a unique position within the broader family of transparent conducting oxides. Its composition, involving cadmium, chlorine, and oxygen, suggests a complex electronic environment that differentiates it from standard binary metal oxides.
While the compound has been identified across multiple structural databases, its thermodynamic status above the hull indicates it is a metastable phase. This characteristic makes it a subject of interest for researchers investigating non-equilibrium synthesis pathways and the limits of structural stability in complex oxide systems.
Key Properties
Cross-validated computational properties for CdCl2O, aggregated across 4 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.

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, CdCl2O is significantly less thermodynamically robust. While materials like BaSnO3 are prized for their high conductivity and structural reliability, CdCl2O represents a more exotic, experimental member of the class that lacks the established industrial utility of its more stable counterparts.
