Three scientists won the Nobel Prize with Blu ray LED

2014 Nobel Prize Winner Announced by the Japanese scholar (Isamu Akasaki), (Hiroshi), Nakamura (Amano), (Shuji) and other three Co winning. Their achievements for the invention of efficient and environmentally friendly Diodes (Light-Emitting, LED), thereby extending the more bright and energy-saving white light. Three scholars contribute to the benefit of the world, was affirmed by the Nobel committee.

Red light LED and green LED has been the emergence of up to half a century, but due to the limitations of the three primary colors in the Blu ray technology is so poor, has been unable to achieve a revolutionary white light. There have been many scientists and industry to try to create Blu ray LED, but 30 years has never been successful.

Until the early 1990s, the development of GaN (Gallium Nitride GaN) crystallization technology with Akasaki Yong, and Amano Hiroshi of the Nagoya University, and then worked at Nichia (Nichia Corporation) Nakamura Shuji together, since the success of semiconductor material, high brightness blue white light LED technology, bring more long-term energy-saving lighting for the world, instead of the traditional containing harmful substances.

Professor, tenured professor at Nagoya University, Akasaki Yong is distinguished professor at the Nagoya University and City University, Amano Hiroshi; and the father of "blue" said Nakamura Shuji, a professor at the University of California-Santa Barbara of the United states. Three Nobel prize winners will share a total of 8 million Swedish kronor (about NT $3390) bonus.

Japan's Nobel prize for physics prize number is Asian anomaly

The results of the physics award, but also to the world over the years in Japan's investment in research and development and admiration. Japan is Asia won the most prize (four Chinese Asian countries won the physics prize, which is a Chinese American physicist, Zhu Diwen, a native of Jiangsu Taicang, born in Saint Louis, but no China nationality; Kao also holds British and American nationality, has a Hongkong resident. Chen Ning Yang, Li Zhengdao is to have the nationality of the Republic of China, the same holds American citizenship), in Japan over the years a total of 22 Nobel prize winners, there are 10 who won the prize for physics, and it is more physics prize winner and racing together bridle to bridle.

The Japanese physics prize generator, there are two major schools. First, the Department of physics, Kyoto University, and the other is the Nagoya University, but also to the invention of the award-winning LED three people, Akasaki Yong and Tian Hao Hao's school.

At the same time, in the case of LED, it was a very short time to be born and commercially viable in 1994. The Nobel prize in physics has been awarded to three of the most important scientists in the development of LED, and the time to develop a blu ray LED from Nakamura Shuji was only a short span of 20 years.

Akasaki Yong is now 85 years old, finally also wait for the Nobel prize, and his followers of Amano Hiroshi is only 54 years old, working with Nakamura Shuji just 60 years old this year, in the academic field there are a lot of space for development.

In 1949, the first winner of the Nobel prize in physics in Japan is Yukawa Hideki (Hideki Yukawa), because the Japanese income tax for bonus tax, so the Japanese public opinion on the Japanese government to fear Yukawa Hideki and impose the Nobel prize a big table against income tax. Therefore, the Japanese government changed the income tax in the same year, all from the academic, art, charity and other social and cultural aspects, contribute and get recognition award winner, also free, no longer being bonus after income tax imposition, is made in the wind.

Nakamura Shuji and Nichia litigation story

Coincidentally, another major change in the field of scientific research in Japan because of the incident, just to win the Nobel prize in Physics related to Mr. Nakamura Shuji.

Nakamura Shuji graduated from Tokushima Industrial University in Japan, and then developed a blu ray LED, is also served in the Nichia company is located in the Tokushima area of four. Nakamura Shuji itself is four people, was born in Ehime prefecture.

When Nakamura Shuji resigned in Ming, in charge of funds and resources to do to give him that can be successful in blue LED, is also the GaN material formulation and process. When the Blu ray LED was successfully made in 1994, the next year will also be able to commercialize the green LED, in 1999 to create a blue violet semiconductor laser (Laser Diode, LD). Nakamura Shuji left Nichia after 2000 was invited to the United States as a professor at the University of California-Santa Barbara.

Nichia because of Nakamura Shuji and other outstanding scientists so to LED sitting posture in many key patents, high quality LED products at the same time through global trafficking, patent litigation against competitors. Nakamura Shuji shocked the Japanese industry events, is put forward in 2001 invention compensation lawsuit against Nichia company. Nakamura Shuji believes that the current development of LED products, despite the use of resources provided by Nichia, but he is the inventor of the patent, should have the relative or reward, and proceedings.

At that time, the incident caused a great uproar. The Tokyo District Court presumed Nichia blue LED due to the benefits of up to 120 billion yen, if Nakamura Shuji's contribution degree calculation by 50%, should be 60 billion 400 million yen for
