Si0.6Ge0.4
semiconductor· Si0.6Ge0.4
Si₀.₆Ge₀.₄ is a silicon-germanium alloy semiconductor with 60% silicon and 40% germanium by composition, engineered to modify bandgap and lattice properties relative to pure silicon. This material is primarily used in high-speed integrated circuits, heterojunction bipolar transistors (HBTs), and advanced optoelectronic devices where the tuned bandgap enables faster carrier transport and improved performance over conventional Si. The Ge-enriched composition makes it particularly valuable for RF/microwave applications, analog integrated circuits, and emerging infrared detector applications where bandgap engineering and enhanced carrier mobility are critical.

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.
