· Ge0.542Si0.458

Ge0.542Si0.458 is a germanium-silicon alloy semiconductor with a composition near the 54:46 atomic ratio, belonging to the IV-IV group of elemental semiconductors. This material is engineered to achieve specific bandgap and lattice properties intermediate between pure silicon and germanium, making it relevant for high-performance optoelectronic and photovoltaic applications where tuned carrier transport and light absorption are critical. The composition sits in a region of practical interest for multi-junction solar cells, infrared detectors, and heterojunction devices where lattice matching and bandgap engineering are design priorities.

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.
