· Ge40Te5.3I8

Ge40Te5.3I8 is a chalcogenide glass semiconductor alloy, part of the germanium–tellurium–iodine family, primarily investigated for phase-change memory (PCM) and infrared photonic applications. This material composition is used in research and development for non-volatile data storage devices and IR optical components, where its amorphous-to-crystalline switching behavior enables reversible, fast switching cycles. The iodine doping modifies the thermal and electronic properties compared to binary Ge-Te systems, making it notable for tuning crystallization kinetics and optical transparency in the mid-IR spectrum.

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.
