semiconductor· Ge0.838Si0.162
Ge0.838Si0.162 is a germanium-silicon alloy semiconductor with a composition heavily weighted toward germanium, belonging to the IV-IV group of the periodic table. This material is primarily investigated for infrared optics and high-speed electronic applications where the germanium-rich composition offers improved performance over pure silicon or standard SiGe ratios. The germanium-rich alloy is notable for its tunable bandgap and refractive index properties, making it valuable for specialized photonic and detector applications where standard silicon is unsuitable, though it remains largely in research and development phases compared to mainstream commercial semiconductors.

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.
