CdCO2
CdCO2 is a metastable, wide-band-gap oxide that serves as a specialized subject of study within the field of transparent conducting materials.
About CdCO2
CdCO2 is a metastable inorganic compound belonging to the class of transparent conducting oxides. Its electronic character is defined by a wide band gap, classifying it as an insulator under standard conditions. The material exhibits structural diversity, with multiple reported configurations across various databases, reflecting its complex energy landscape.
This compound is of interest to researchers studying the fundamental properties of oxides that bridge the gap between insulating behavior and potential conductivity. Its metastable nature makes it a subject of investigation for advanced materials synthesis and thin-film development in optoelectronic applications.
Key Properties
Cross-validated computational properties for CdCO2, 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.
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.

How It Compares
Within the transparent conducting oxides class.
While many members of this class, such as ZnO and BaSnO3, are widely utilized for their robust conductive properties, CdCO2 remains a more exotic and metastable entry. Unlike the highly stable spinel structures like ZnGa2O4 or ZnCr2O4, CdCO2 represents a less conventional stoichiometry that challenges standard synthesis routes for transparent oxides.
