CdSe2O5 is a stable, semiconducting transparent conducting oxide that provides a unique structural alternative to more common binary oxide materials.
About CdSe2O5
CdSe2O5 is a thermodynamically stable inorganic compound that belongs to the class of transparent conducting oxides. Characterized by its semiconducting electronic nature, this material represents a distinct structural arrangement within the cadmium-selenium-oxygen system, offering unique potential for electronic and optoelectronic applications.
As a material that sits on the convex hull, CdSe2O5 demonstrates significant structural integrity. Its existence across multiple reported databases highlights its importance as a subject of ongoing research into complex oxide semiconductors that balance optical transparency with controlled charge carrier behavior.
Key Properties
Cross-validated computational properties for CdSe2O5, 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.

How It Compares
Within the transparent conducting oxides class.
While many members of the transparent conducting oxide class, such as ZnO or BaSnO3, are widely utilized for their high conductivity and established industrial utility, CdSe2O5 offers a more specialized structural profile. Unlike the simpler binary oxides in this group, CdSe2O5 features a more complex coordination environment that distinguishes it from the spinel-structured siblings like ZnGa2O4 or ZnCr2O4.
