About Zinc oxide
Zinc oxide is a thermodynamically stable semiconducting material that serves as a cornerstone in modern materials science. Its robust electronic structure and high structural versatility make it a preferred candidate for various catalytic and optoelectronic applications.
Because it resides on the convex hull, this compound exhibits exceptional stability, ensuring reliable performance in demanding chemical environments. It is widely utilized in industrial processes where its surface reactivity and electronic properties can be precisely tuned.
Key Properties
Cross-validated computational properties for Zinc oxide, 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.
