cadmium stannate · cadmium tin trioxide
CdSnO3 is a stable, semiconducting transparent conducting oxide used in the development of optoelectronic and sensing technologies.
About cadmium stannate
CdSnO3 is a thermodynamically stable ternary oxide that functions as a transparent conducting oxide. Its semiconducting electronic character makes it a subject of significant interest for researchers looking to balance optical transparency with electrical conductivity in thin-film devices.
Because it resides on the convex hull, this material exhibits robust structural integrity. Its versatility is highlighted by the numerous reported crystal structures, which provide a rich foundation for tailoring its performance in various electronic and sensing applications.
Key Properties
Cross-validated computational properties for cadmium stannate, 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.
