CaIn2O4
CaIn2O4 is a thermodynamically stable semiconducting oxide used in the study and development of transparent electronic materials.
About CaIn2O4
CaIn2O4 is a complex oxide that functions as a semiconductor. Its position on the convex hull indicates high thermodynamic stability, making it a robust candidate for materials science research and potential integration into advanced electronic systems. As a member of the transparent conducting oxide family, it is investigated for its ability to balance electrical conductivity with optical transparency. This material is particularly relevant for developers seeking stable, wide-gap semiconductors that can withstand various processing conditions.
Key Properties
Cross-validated computational properties for CaIn2O4, 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.
