Ge0.7Si0.3
semiconductor· Ge0.7Si0.3
Ge0.7Si0.3 is a germanium-silicon alloy semiconductor composed of 70% germanium and 30% silicon, combining the electronic properties of both group IV elements. This material is primarily of research and developmental interest for advanced optoelectronic and high-speed electronic devices, where the tunable bandgap and carrier mobility between pure germanium and silicon can be engineered for specific performance requirements. It competes with or complements pure Ge and SiGe (silicon-germanium) alloys in applications requiring tailored electronic or photonic properties, though commercial deployment remains limited compared to mature Si or SiGe technologies.

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.
