· Hg0.01Cd0.99Se

Hg₀.₀₁Cd₀.₉₉Se is a mercury-cadmium selenide alloy, a narrow-bandgap II-VI semiconductor compound in which a small fraction of cadmium is substituted with mercury. This material is primarily investigated in research contexts for infrared detection and sensing applications, where the mercury dopant fine-tunes the bandgap energy to target specific wavelength regions in the mid-to-long-wave infrared spectrum. Relative to undoped CdSe or pure HgCdTe, the mercury-cadmium selenide platform offers tunable optoelectronic properties and is notable for potential use in thermal imaging, spectroscopy, and space-based infrared instrumentation, though commercial adoption remains limited due to processing complexity and the cost-benefit trade-off compared to established mercury-cadmium telluride (MCT) alternatives.

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.
