Key Properties
Cross-validated computational properties for zinc sulfate, 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.
Unlike the highly conductive ZnO, which is a hallmark of the transparent conducting oxide family, ZnSO4 functions primarily as a wide-gap insulator. While materials like BaSnO3 are engineered for specific electronic transport properties, ZnSO4 is distinguished by its role as a stable, non-conductive zinc-based compound within the class.
