· Se0.4Te0.6

Se0.4Te0.6 is a binary semiconductor alloy combining selenium and tellurium in a 40:60 composition ratio, belonging to the chalcogenide family of materials. This compound is primarily investigated for infrared (IR) optics and thermal imaging applications, where its tunable bandgap and transmission properties in the mid- to far-infrared spectrum make it an alternative to pure tellurium or germanium-based systems. The material is also of interest for thermoelectric devices and phase-change memory applications, though it remains largely in the research and specialized device phase rather than high-volume production.

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.
