· K2HgP2Se6

K2HgP2Se6 is a ternary semiconductor compound combining potassium, mercury, phosphorus, and selenium elements, belonging to the family of heavy-metal chalcogenide semiconductors. This is primarily a research material investigated for its nonlinear optical properties and potential mid-infrared photonic applications; it is not yet widely deployed in commercial products. The material's mercury and selenium composition positions it within an experimental class of compounds studied for frequency conversion, laser systems, and radiation detection, though practical adoption remains limited due to toxicity concerns and competing established alternatives in these markets.
