HgWO4
HgWO4 is a semiconducting mercury tungstate compound that is considered thermodynamically accessible for experimental synthesis.
About HgWO4
HgWO4 is a ternary inorganic compound composed of mercury, tungsten, and oxygen. As a semiconducting material, it exhibits electronic properties that distinguish it from simple binary oxides, positioning it as a subject of interest for specialized optoelectronic or catalytic research.
Its status as a near-hull compound suggests that it is energetically accessible and likely synthesizable under controlled laboratory conditions. With multiple reported structures across major databases, it remains a material of significant structural interest for researchers exploring complex metal tungstates.
Key Properties
Cross-validated computational properties for HgWO4, 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.
