· Si0.12Ge0.88

Si₀.₁₂Ge₀.₈₈ is a silicon-germanium alloy with high germanium content, belonging to the IV-IV semiconductor family used primarily in optoelectronic and high-speed electronic devices. This composition is engineered to achieve specific bandgap and lattice properties intermediate between pure germanium and silicon, making it valuable for infrared detection, photodiodes, and heterojunction bipolar transistors (HBTs) where performance at wavelengths beyond silicon's range is required. The high Ge fraction positions this alloy for applications demanding enhanced carrier mobility and thermal stability compared to Si-rich SiGe variants, though it represents a specialized research-grade or production material rather than a commodity semiconductor.

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.
