Shuji Nakamura

Niji Nakamura, born on May 22, 1954 in Ifancho, Japan, graduated from Tokushima University in Japan. He is a Japanese American electronic engineer and a professor in the Materials Department of the School of Engineering at the University of California, Santa Barbara, USA. During his tenure at Niya Chemical Industry Co., Ltd. in 1993, Nakamura Hideyoshi developed a high brightness blue LED based on GaN, which became widely known. At that time, developing a blue LED was considered impossible, as there had been only red and green LEDs for the previous 20 years. On October 7, 2014, Hiroshi Akasaki, Hiroshi Amano, and Xiuji Nakamura won the 2014 Nobel Prize in Physics for their invention of efficient blue light-emitting diodes. Yuji Nakamura is the famous inventor of blue LED and blue light LD, which can also be used for blue light discs and HD DVDs. Professor Nakamura's invention is hailed as one of the most important achievements in the semiconductor field of materials science in the past 30 years. The energy used by LEDs is only one-seventh that of incandescent lamps and can last for about 100 times its length, up to 100000 hours. If promoted, it can save a lot of energy and reduce carbon emissions. Hideyoshi Nakamura obtained a Bachelor's, Master's, and Doctoral degree in Electronic Engineering from Tokushima University in 1977, 1979, and 1994. In 1979, he joined Japan Nippon Chemical Industry Co., Ltd. He developed the first batch of high brightness blue and green LEDs based on three group nitrogen materials in 1993 and 1995. In 1995, the first batch of purple laser diodes based on three group nitrogen materials were also invented. Xiuji Nakamura has been a professor at the School of Materials, Electronics, and Computer Engineering at the University of California, Santa Barbara, USA since 2000. Hideyoshi Nakamura was awarded the 2014 Nobel Prize in Physics for his invention of efficient blue light-emitting diodes that enabled the use of bright and energy-saving white light sources. Professor Nakamura's research on blue LEDs began with the use of group III nitride materials. In 1993 and 1995, he developed blue\/green LEDs based on Group III nitrides. In 1995, he also developed Group III nitride based purple laser diodes (LDs). He has won multiple awards, including the PeopleSoft Memorial Award in 1996, the UK Ranking Award in 1998, the Benjamin Franklin Medal in 2002, the Millennium Technology Award in 2006, the Harvey Award in 2009, and the Technology and Engineering Emmy Award in 2012. In 2003, he was elected as a member of the National Academy of Sciences of the United States for engineering. Since 2000, Professor Nakamura has become a professor in the Materials Department and research director of the Solid State Lighting and Energy Center at the University of California, Santa Barbara. He holds over 100 patents in this field and has published over 400 papers.
