· 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.

RoHS, REACH, and Prop 65 statuses are validated against official substance lists (ECHA SVHC Candidate List, OEHHA Prop 65, RoHS Annex II). Other regulations are estimated from composition and material classification. All screening is a starting point for due diligence — always verify with your supplier before making compliance decisions.
