- Light-emitting diode
Blue LEDs have an active region consisting of one or more InGaN quantum wells sandwiched between thicker layers of GaN, called cladding layers. By varying the relative In/Ga fraction in the InGaN quantum wells, the light emission can in theory be varied from violet to amber.
Isamu Akasaki (赤﨑 勇, Akasaki Isamu, January 30, 1929 – April 1, 2021) was a Japanese engineer and physicist, specializing in the field of semiconductor technology and Nobel Prize laureate, best known for inventing the bright gallium nitride p-n junction blue LED in 1989 and subsequently the high-brightness GaN blue LED as well.
8 kwi 2021 · A practical blue LED was a holy grail of photonics. Light emission from semiconductors goes back to 1907, when radio pioneer Henry J. Round saw it from silicon carbide, although he did not know what caused it. Half a century later physicist and IEEE Medal of Honor recipient Nick Holonyak Jr. invented practical red LEDs.
