· Na2Hg3Se1.49S2.51

Na2Hg3Se1.49S2.51 is a mixed-anion semiconductor compound combining sodium, mercury, selenium, and sulfur in a complex chalcogenide structure. This is an experimental/research material rather than a commercial product, belonging to the family of mercury chalcogenides that show promise for infrared optics, photodetection, and potential thermoelectric applications due to their tunable bandgap and mixed anionic composition.
