· Zn0.8Hg0.2Se1

Zn₀.₈Hg₀.₂Se is a ternary semiconductor alloy in the II–VI compound family, combining zinc selenide with mercury selenide to form a mixed-cation material. This composition falls within the mercury cadmium telluride (MCT) family's broader class and is primarily explored for infrared detection and optoelectronic applications, where the mercury content modifies the bandgap relative to pure ZnSe. The material remains largely in research and development phases, used in specialized photonic and thermal imaging systems where tunable infrared sensitivity is required; mercury-containing semiconductors have seen declining industrial adoption due to toxicity and handling concerns, but continue in niche applications where their unique electronic properties cannot be matched by cadmium-free alternatives.

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.
