Hg0.2Cd0.8Se
semiconductor· Hg0.2Cd0.8Se
Hg0.2Cd0.8Se is a mercury-cadmium-selenide ternary alloy semiconductor belonging to the II-VI compound family, engineered to tune the bandgap between cadmium selenide and mercury selenide endmembers. This material is primarily used in infrared detector and imaging systems, particularly in the 8–14 μm wavelength range (long-wavelength infrared), where its narrow tunable bandgap enables room-temperature or lightly-cooled operation. Its strategic position in the II-VI phase space makes it valuable for thermal imaging, spectroscopy, and military/surveillance applications where alternative detector materials (InSb, HgCdTe with different compositions) may be less suitable.

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.
