· Cl4 Se4 Hg6

Cl₄Se₄Hg₆ is a mercury-based mixed-halide semiconductor compound combining chlorine, selenium, and mercury in a layered or cluster structure. This is primarily a research material investigated for its semiconductor and optoelectronic properties rather than a widely commercialized engineering material; compounds in this family are of interest for photovoltaic applications, photodetectors, and solid-state electronics due to their tunable bandgap and potential for solution processing. Engineers would consider this material in early-stage device development where mercury-based semiconductors offer advantages in sensitivity or wavelength response, though toxicity, environmental regulations, and manufacturing complexity present significant practical constraints compared to lead halide perovskites or traditional III–V semiconductors.

Export Control

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.
