· Hg4 W4 O14

Hg₄W₄O₁₄ is a mixed-metal oxide semiconductor compound containing mercury and tungsten. This material belongs to the class of polymetallic oxides and is primarily of research interest for its potential electronic and photocatalytic properties within the broader family of tungsten-based and mercury-containing semiconductors. Applications remain largely experimental, with investigation focused on photocatalysis, sensing, and potential optoelectronic devices where the combination of mercury and tungsten oxides may offer tunable band gaps or enhanced charge-carrier dynamics.
