· Se0.5Te0.5

Se₀.₅Te₀.₅ is a selenium-tellurium alloy semiconductor compound with a 1:1 composition ratio, belonging to the chalcogenide family of materials. This is primarily a research and emerging-technology material used in infrared optics, thermoelectric devices, and radiation detection applications where its narrow bandgap and tunable electronic properties offer advantages over single-element alternatives. The 50/50 composition represents a specific point in the Se-Te phase diagram optimized for particular optical or thermal conversion characteristics, making it of interest to researchers developing next-generation infrared sensors and energy harvesting systems.

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.
