· Si0.7Ge0.3

Si₀.₇Ge₀.₃ is a silicon-germanium alloy semiconductor with 70% silicon and 30% germanium, engineered to balance the electronic properties of both elements for enhanced performance in high-speed applications. This material is primarily used in advanced optoelectronic and high-frequency devices where improved carrier mobility and direct bandgap characteristics are advantageous; it is particularly notable in heterojunction bipolar transistors (HBTs), integrated photodetectors, and fiber-optic communication components where it outperforms pure silicon in speed and sensitivity. The strained-layer SiGe alloy system is also significant in research for thermoelectric devices and next-generation transistor architectures, offering engineers a tunable materials platform between silicon's mature processing infrastructure and germanium's superior electron transport.

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.
