V2Cd2O7
V2Cd2O7 is a thermodynamically stable semiconducting oxide used in materials science research for its potential in electronic and optoelectronic applications.
About V2Cd2O7
V2Cd2O7 is a complex oxide that sits firmly on the thermodynamic convex hull, indicating high structural stability. As a member of the transparent conducting oxide family, it exhibits semiconducting behavior that makes it a subject of interest for advanced electronic and optoelectronic material research.
Its structural diversity is evidenced by multiple reported crystallographic configurations across major databases. This versatility allows researchers to explore its potential in applications where stable, semiconducting oxide thin films or bulk materials are required for next-generation device integration.
Key Properties
Cross-validated computational properties for V2Cd2O7, 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.
Unlike the widely utilized ZnO, which is a standard industry workhorse for transparent conductivity, V2Cd2O7 represents a more specialized, complex oxide architecture. While materials like BaSnO3 are often highlighted for their high carrier mobility, V2Cd2O7 offers a distinct structural framework that broadens the design space for semiconducting oxides beyond the simple binary or common spinel structures like ZnGa2O4.
