· Cd0.01Hg0.99Se1

Cd0.01Hg0.99Se is a mercury-cadmium-selenide (MCdSe) narrow-bandgap semiconductor alloy, where cadmium substitutes approximately 1% of the mercury sites in the HgSe lattice. This material belongs to the II-VI semiconductor family and is primarily of research and specialized infrared detector interest, with the cadmium doping modulating the bandgap energy relative to pure HgSe. MCdSe alloys have historically been used in infrared detection and imaging applications where tunable bandgap energy in the mid- to long-wavelength infrared (MWIR/LWIR) range is required, though environmental and health concerns regarding mercury and cadmium have motivated transition toward alternative materials like HgCdTe variants with reduced heavy-metal content or cadmium-free compounds.

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.
