Cu4 Hg4 Se4 Br4
semiconductor· Cu4 Hg4 Se4 Br4
Cu4Hg4Se4Br4 is a quaternary chalcohalide semiconductor compound combining copper, mercury, selenium, and bromine elements. This is a research-stage material rather than an established commercial compound; it belongs to the broader family of mixed-metal chalcohalides that are being investigated for their semiconductor and optoelectronic properties. The material's potential lies in photovoltaic devices, photodetectors, or other light-harvesting applications where the combination of heavy metal centers (Hg) and mixed anion coordination could produce useful electronic band structures or charge-transport characteristics distinct from more conventional semiconductors.
