· LaP

Lanthanum phosphide (LaP) is a binary III-V semiconductor compound combining a rare-earth element with phosphorus, belonging to the wider family of phosphide semiconductors. It is primarily of interest in advanced optoelectronic and high-frequency electronic device research, where rare-earth phosphides are explored for their potential in infrared emitters, quantum well structures, and specialized heterostructure applications. Compared to common III-V semiconductors like GaAs or InP, LaP offers a distinct bandgap and lattice parameter profile that may enable novel device designs, though it remains largely in the research and development phase rather than high-volume production.

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.
