· Ge0.1Si0.9

Ge0.1Si0.9 is a germanium-silicon alloy containing 10% germanium and 90% silicon, belonging to the IV-IV semiconductor compound family. This material is primarily of research and developmental interest for advanced optoelectronic and high-speed electronic applications where lattice-engineered bandgap tuning offers advantages over pure silicon. The germanium addition modifies the electronic and optical properties of silicon, making it relevant for integrated photonics, infrared detectors, and next-generation CMOS technologies where performance beyond conventional silicon limits is needed.

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.
