· GaN· Gallium Nitride

Gallium Nitride (GaN) is a wide-bandgap semiconductor compound composed of gallium and nitrogen, belonging to the III-V nitride family of materials. It is the dominant material for high-brightness blue and ultraviolet LEDs, RF power amplifiers, and next-generation power electronics converters, where its wide bandgap enables high operating temperatures, high switching frequencies, and superior energy efficiency compared to silicon-based alternatives. Engineers select GaN for applications demanding high power density, fast switching performance, and thermal stability in compact form factors.

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.
