Si0.1Ge0.9
semiconductor· Si0.1Ge0.9
Si₀.₁Ge₀.₉ is a silicon-germanium alloy heavily weighted toward germanium (90%), belonging to the group IV semiconductor family. This material is engineered to achieve germanium-like electronic properties while incorporating small amounts of silicon to modulate bandgap, lattice constant, and thermal characteristics for specific device applications. It is primarily used in high-speed optoelectronic and infrared detector applications, where the germanium-rich composition enables efficient light absorption in the near-infrared and mid-infrared regions while silicon incorporation helps manage lattice matching to silicon substrates and improve thermal stability compared to pure germanium.

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.
