How Do LED Lights Do What They Do | Electronics360

The p-n junction is constructed from a semiconductor such as gallium nitride (GaN), gallium arsenide (GaAs), gallium arsenide phosphide (GaAsP) or gallium phosphide (GaP). Each side of the junction is doped. A p-type semiconductor is made by doping the semiconductor with acceptor impurities while an n-type is made by doping with donor impurities.

Boron nitride - WikiMili, The Best Wikipedia Reader

2020-6-30 · Boron nitride is a thermally and chemically resistant refractory compound of boron and nitrogen with the chemical formula BN.It exists in various crystalline forms that are isoelectronic to a similarly structured carbon lattice. The hexagonal form corresponding to graphite is the most stable and soft among BN polymorphs, and is therefore used as a lubricant and an additive to cosmetic products.

Boron - Wikipedia

2  · Boron is a chemical element with the syol B and atomic nuer 5. Produced entirely by cosmic ray spallation and supernovae and not by stellar nucleosynthesis, it is a low-abundance element in the Solar System and in the Earth''s crust. It constitutes about 0.001 percent by weight of Earth’s crust. Boron is concentrated on Earth by the water-solubility of its more common naturally occurring
