· Hg0.99Cd0.01Se

Hg0.99Cd0.01Se is a narrow-bandgap II-VI semiconductor alloy composed primarily of mercury selenide with 1 mol% cadmium doping, belonging to the HgCdSe family of infrared-sensitive materials. This alloy is primarily used in infrared detectors and thermal imaging systems operating in the mid- to long-wavelength infrared (MWIR/LWIR) range, where its tunable bandgap and high sensitivity to thermal radiation make it valuable for military, aerospace, and scientific applications. The cadmium incorporation provides bandgap engineering capability, allowing optimization of spectral response compared to pure HgSe, though HgCdSe materials remain challenging to process and are typically reserved for demanding applications where performance justifies the manufacturing complexity.

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.
