Gallium Nitride is a binary III/V direct bandgap semiconductor that is well-suited for high-power transistors capable of operating at high temperatures. Since the 1990s, it has been used commonly in light emitting diodes (LED). Gallium nitride gives off a blue light used for disc-reading in Blu-ray.

A blue laser is a laser that emits electromagnetic radiation with a wavelength between 360 and 480 nanometers, which the human eye sees as blue or violet.. Blue beams are produced by helium-cadmium gas lasers at 441.6 nm, and argon-ion lasers at 458 and 488 nm. Semiconductor lasers with blue beams are typically based on gallium(III) nitride (GaN; violet color) or indium gallium nitride (often ...

Abstract It is shown that the strong enhancement of the Earth (day-night) effect for solar neutrinos crossing the Earth core in the case of the small mixing angle MSW νe→νμ(τ) transition solution of the solar neutrino problem is due to a new resonance effect in the solar neutrino transitions in the Earth and not just to the MSW effect in the core. The effect is in many respects similar ...
