· Te0.8Se0.2

Te0.8Se0.2 is a tellurium-selenium alloy semiconductor in the chalcogenide family, where tellurium is the primary constituent with 20% selenium substitution. This material is primarily explored in research and emerging applications rather than established industrial production, leveraging the thermal and electrical properties of the Te-Se system for specialized semiconductor devices. The selenium doping modifies the bandgap and crystalline structure of tellurium, making it relevant for infrared optics, thermoelectric energy conversion, and radiation detection where the tuned composition offers advantages over pure tellurium or selenium alone.

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.
