· Hg2

Hg2 is a mercury-based semiconductor compound that belongs to the mercury chalcogenide family of materials. This material is primarily of research and specialized industrial interest, studied for infrared detection and optoelectronic applications where its narrow bandgap properties enable sensitivity in the infrared spectrum. It represents an alternative to more conventional semiconductors in niche applications where mercury-based compounds offer advantages in thermal imaging, night-vision systems, and specialized sensor technologies, though practical deployment remains limited compared to mainstream semiconductors due to toxicity and handling constraints.

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.
