About Shuji Nakamura
Shuji Nakamura (Japanese: 中村 修二, romanized: Nakamura Shūji; born May 22, 1954) is a Japanese–American electronics engineer and co-inventor of the blue LED, a major breakthrough in lighting technology. For this achievement, Nakamura, together with Isamu Akasaki and Hiroshi Amano, received the Nobel Prize in Physics in 2014. Nakamura specializes in the field of semiconductor technology. He is Professor of Materials and of Electrical and Computer Engineering at the University of California, Santa Barbara (UCSB) since 1999. == Career and research == Nakamura graduated from the University of Tokushima in 1977 with a B.Eng. in Electronic Engineering, and obtained an M.Eng. in the same subject in 1979, after which he joined the Nichia Corporation, also based in Tokushima. It was while working for Nichia that Nakamura invented the method for producing the first commercial high brightness gallium nitride (GaN) LED whose brilliant blue light, when partially converted to yellow by a phosphor coating, is the key to white LED lighting, which went into production in 1993. Previously, J. I. Pankove and co-workers at RCA put in considerable effort but did not make a marketable GaN LED in the 1960s. The principal problem was the difficulty of making strongly p-type GaN. Nakamura drew on the work of another Japanese group led by Professor Isamu Akasaki, who published their method to make strongly p-type GaN by electron-beam irradiation of magnesium-doped GaN; however, this method was not suitable for mass production.
