Indium Phosphide (InP)
Verifiedsemiconductor· InP· Indium Phosphide
Indium phosphide (InP) is a III-V binary compound semiconductor with a direct bandgap, widely recognized for high-speed and high-frequency device performance. It is the material of choice for optoelectronic and RF applications where superior electron mobility and saturation velocity enable operation at frequencies and data rates that exceed silicon and gallium arsenide alternatives. InP's direct bandgap makes it especially valuable for integrated photonics, long-wavelength infrared detectors, and millimeter-wave integrated circuits used in telecommunications, aerospace, and emerging 5G/6G 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.
