· Cd0.204Hg0.796Te1

Cd₀.₂₀₄Hg₀.₇₉₆Te is a cadmium-mercury telluride (CMT) alloy, a narrow-bandgap semiconductor engineered for infrared detection by controlling the cadmium-to-mercury ratio to tune the bandgap energy. This specific composition targets the mid-to-long wavelength infrared (MWIR/LWIR) detection window and is primarily used in research and specialized defense/aerospace thermal imaging systems where high sensitivity to infrared radiation is critical. CMT alloys compete with alternative infrared detectors like InSb and microbolometers, but offer superior performance in cooled detector applications due to their tunable bandgap and mature heterostructure technology.

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.
