Description and Uses
Mercury(II) selenide is used in semiconductors, infrared detectors, solar cells, transistors and amplifiers. It is also used as filters in some steel plants in order to remove mercury from exhaust gases. Further, it is used as an ohmic contact to wide-gap II-VI semiconductors such as zinc selenide or zinc oxide.
