· Ge8 As8 Se8

Ge8As8Se8 is a chalcogenide glass semiconductor composed of germanium, arsenic, and selenium in near-equiatomic proportions. This material belongs to the family of amorphous chalcogenide semiconductors, which are primarily of research and specialized industrial interest rather than high-volume commercial use. Chalcogenide glasses like this composition are investigated for infrared optics, nonlinear photonics, and phase-change memory applications due to their transparency in the mid- to far-infrared spectrum and switchable electronic properties, though they remain less common than their binary counterparts (such as GeSe or As2Se3) in established manufacturing.

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.
