· Te0.5Se0.5

Te₀.₅Se₀.₅ is a binary chalcogenide semiconductor alloy composed of equal atomic fractions of tellurium and selenium, belonging to the Group VI elemental semiconductor family. This material is primarily investigated in research contexts for infrared optics, thermoelectric devices, and next-generation photovoltaic applications, where its tunable bandgap and thermal properties offer advantages over pure tellurium or selenium alone. The 1:1 composition represents a strategic balance point in the Te-Se phase diagram, making it relevant for engineers developing narrowband infrared detectors, thermal imaging systems, and solid-state cooling devices where the intermediate electronic and phononic properties outperform single-element 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.
