Hg0.6Cd0.4Se
semiconductor· Hg0.6Cd0.4Se
Hg₀.₆Cd₀.₄Se is a narrow-bandgap semiconductor alloy belonging to the II-VI compound family, formed by combining mercury selenide and cadmium selenide in a 60:40 molar ratio. This material is primarily of research and specialized industrial interest for infrared optoelectronics, where its bandgap falls in the mid-wave infrared (MWIR) region, making it valuable for thermal imaging and infrared detection applications. Engineers select this alloy when room-temperature or near-room-temperature infrared sensitivity is needed without complex cooling systems, though its use is limited by mercury toxicity concerns and the availability of alternative materials like lead chalcogenides and HgCdTe with optimized compositions.

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.
