· Cu4 Hg4 S4 Br4

Cu4Hg4S4Br4 is a mixed-halide chalcogenide semiconductor compound containing copper, mercury, sulfur, and bromine elements. This is an experimental research material rather than a commercially established compound, belonging to the family of metal chalcogenide semiconductors that are of interest for optoelectronic and photonic device development. The combination of mercury and bromine with copper sulfide creates a complex semiconductor structure potentially relevant to next-generation light emission, photodetection, or nonlinear optical applications where tunable bandgaps and multiple-component systems offer advantages over single-element semiconductors.
