· GeSi

GeSi is a semiconductor alloy combining germanium and silicon, engineered to create a tunable bandgap material that bridges the properties of its parent semiconductors. It is primarily used in optoelectronic and high-speed electronic devices where the ability to customize energy bandgap through composition variation offers advantages over single-element alternatives, and serves as a key material platform for heterojunction structures in advanced device architectures.

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.
