· Ge0.02Si0.98

Ge0.02Si0.98 is a germanium-silicon alloy containing approximately 2% germanium and 98% silicon, belonging to the group IV semiconductor family. This material is used primarily in advanced optoelectronic and high-performance electronic devices where the small germanium addition to silicon provides enhanced carrier mobility and reduced bandgap compared to pure silicon, enabling faster switching and improved infrared response. The composition sits at the lower end of the germanium-silicon spectrum, making it relevant for applications requiring moderate performance improvements over standard silicon while maintaining compatibility with existing silicon processing infrastructure.

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.
