Silicon (Si)
Verifiedsemiconductor· Si· Silicon· c-Si· Crystalline Silicon
Silicon is a crystalline semiconductor element that forms the foundation of modern microelectronics and photovoltaics. It is the primary material for integrated circuits, discrete transistors, and solar cells due to its ability to be precisely doped and processed into p-n junctions that control electrical current. Beyond electronics, silicon is valued in MEMS (micro-electromechanical systems), optical applications, and high-temperature structural uses where its combination of strength, thermal stability, and controlled electrical properties outperform metals and insulators.

Export Control
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.
