semiconductor· Cd0.28Hg0.72Te1
Cd₀.₂₈Hg₀.₇₂Te is a cadmium mercury telluride (CMT) alloy, a narrow-bandgap II-VI semiconductor engineered for infrared detection by precise control of the cadmium-to-mercury ratio. This material is the industry standard for thermal imaging and long-wavelength infrared sensing in the 8–14 µm atmospheric window, where its tunable bandgap outperforms alternatives like InSb or cooled silicon detectors in terms of spectral range and quantum efficiency. The specific Cd:Hg ratio of approximately 28:72 positions this composition in the mid-to-long-wave infrared regime, making it essential for demanding applications requiring sensitivity at cryogenic operating temperatures.

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.
