Isamu Akasaki (赤崎 勇, Akasaki Isamu; January 30, 1929 – April 1, 2021) was a Japanese materials scientist specializing in the field of semiconductor technology. He is best known for co-inventing the bright gallium nitride (GaN) p–n junction blue LED in 1989 and subsequently the high-brightness GaN blue LED as well. Akasaki was awarded the 2014 Nobel Prize in Physics, along with Hiroshi Amano and Shuji Nakamura, "for the invention of efficient blue light-emitting diodes which has enabled bright and energy-saving white light sources."
