semiconductor· Hg0.25Zn0.75Te
Hg0.25Zn0.75Te is a cadmium-free II-VI semiconductor alloy combining mercury telluride and zinc telluride, engineered to operate in the infrared spectrum. This material is primarily used in infrared detector arrays and thermal imaging systems where sensitivity in the mid- and long-wave infrared regions is required, and it offers a lower bandgap than zinc telluride alone while avoiding the toxicity and regulatory constraints of cadmium telluride. The alloy is notable for enabling compact, sensitive infrared sensing in defense, thermal surveillance, and scientific instrumentation applications.

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.
