Si0.8Ge0.2
semiconductor· Si0.8Ge0.2
Si0.8Ge0.2 is a silicon-germanium alloy semiconductor composed of 80% silicon and 20% germanium, representing a controlled composition within the SiGe material system. This alloy is engineered to modify semiconductor properties relative to pure silicon, particularly for applications requiring enhanced carrier mobility and tuned bandgap characteristics. SiGe alloys are used in high-speed integrated circuits, RF/microwave devices, and optoelectronic applications where the performance advantages of germanium can be accessed while leveraging silicon's manufacturing infrastructure and cost economics.

Export Control
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.
