· InN

Indium nitride (InN) is a wide-bandgap III-V semiconductor compound with a hexagonal wurtzite crystal structure, belonging to the nitride family alongside GaN and AlN. It is primarily used in high-frequency and optoelectronic devices, particularly in RF power amplifiers, high-electron-mobility transistors (HEMTs), and emerging photovoltaic applications where its narrow bandgap (smaller than GaN) enables operation in the infrared spectrum. InN remains largely in research and early-stage commercialization phases compared to mature GaN technology, but its potential for tunable bandgap engineering in heterostructures and high-frequency applications at microwave and millimeter-wave frequencies makes it attractive for next-generation wireless and sensing systems.

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.
