The Nobel Prize in Physics 2014 blue LED shine! Japan's three shared-winning inventor.

The Nobel Prize in Physics 2014: Nobel Laureate in Physics announced, Japanese scholars three co-winners by Isamu Akasaki, Hiroshi Amano, Shuji Nakamura. Their achievement was the invention of high-performance and environmental friendly blue light-emitting diode (Light-Emitting Diodes, LED), thus extending a brighter energy-efficient white light illumination. The three scholars for the benefit of the contribution of the world, won the Nobel Committee affirmed.

Japan's three shared Nobel winner inventor

Red LED and green LED's emergence has been over half a century, but is limited due to the poor of the three primary colors of the Blu-ray technology it has been unable to reach a revolutionary white lighting. There have been many attempts to manufacture scientists and industry insiders blue LED, but 30 years ago has never been successful.

Until the early 1990s, the development of crystallization technology Isamu Akasaki, working together with the same at Nagoya University (Amano ho) and then worked at Nichia (Nichia Corporation) of Shuji Nakamura, a successful self- semiconductor materials research and development of high-brightness blue LED technology, for the world to bring more long-lasting energy-efficient white lighting, replace traditional lighting fixtures containing hazardous substances.

 Assembly Special to the blue LED lights, the founder of the Nobel Prize spell "Alfred Nobel" of initials

Isamu Akasaki, incumbent tenured professor at Meijo University, Nagoya University Distinguished Professor, Hiroshi Amano is currently a professor at Nagoya University; while the "Father of the blue," said Shuji Nakamura, now a professor at the University of California, Santa Barbara. Three Nobel laureates will share the award, winning eight million Swedish kronor (about NT $ 33.9 million) in prize money.

Japan's Nobel Prize in Physics winning number is the number of different Asian

The physics prize results, but also to the world of Japanese investment and the development of these years on R & D was impressed. Japan is a country in Asia to get the most physical Award (Asia there are four Chinese get physical prize, which is a Chinese-American physicist Steven Chu, a native of Jiangsu Taicang, was born in St. Louis, but no Chinese nationality; Kao with Britain and the United States nationality, owned by Hong Kong resident status. Chen Ning Yang, Tsung-Dao Lee is with ROC nationality, the same holds U.S. citizenship) in Japan over the years, a total of 22 Nobel Prize winners, there are 10 to get a physical prize, can be said with Physics Prize winner in Europe and America more to keep pace.

Japan's physics prize winner, there are two schools. First, Kyoto University, Department of Physics, Nagoya University, the other is also in this award-winning trio LED invention, Isamu Akasaki and Hiroshi Amano is employed by the school.

Meanwhile, LED invention, born from 1994 to commercialize a truly viable and time is very short. The Nobel Prize in Physics was awarded to LED development very important three scientists from Shuji Nakamura developed a blue LED time, only a short period of 20 years.

Isamu Akasaki is now 85 years-old, until finally the Nobel Prize, and his after school Hiroshi Amano is now only 54 years old, to cooperate with Shuji Nakamura is just 60 years old this year, there are many available in the academic field of space development.

2014 Nobel Prize in Physics

1949, the first winner of Nobel Prize in Physics was awarded Japan Hideki Yukawa,

Therefore, at the end of the same year, the Japanese government revised the Income Tax Act, all from the academic, skills, charitable and other cultural and social aspects, resulting in recognition of the contribution and get bonus winner, are to be tax-free, then suffered another bonus without having to levy income tax, considered legislation Under a good wind.

Coincidentally, another Japanese major change for scientific research and industry events coincided with the award of the Nobel Prize in Physics for this Mr. Shuji Nakamura relevant.

Shuji Nakamura graduated from Japan Shikoku Tokushima University while the year to develop a blue LED, also is located in Tokushima, Shikoku regions Nichia Corporation office. Shuji Nakamura itself is four people, is the birthplace of Ehime Prefecture.

Shuji Nakamura is then resigned Ming, director of grant funding and resource requirements of doing what he can successfully convince the blue LED, which is GaN material aspects of the formulation and process. 

When the blue LED successfully made in 1994, every year has also made commercially viable green LED, 1999 years and to create a blue-violet semiconductor laser (Laser Diode, LED). Shuji Nakamura after leaving Nichia, 2000 invited to the University of California, Santa Barbara professor.

Nichia because of Shuji Nakamura and other outstanding scientists of it to sitting posture LED key patents, sales of many high-quality LED products in the world, and through patent litigation against competitors. The incident shocked Shuji Nakamura Japanese industry is 2001 Nichia Corporation proposed to pay gold litigation invention. Shuji Nakamura believes that the development of LED products during the year, despite the use of the resources provided by Nichia, but he is the inventor of the patent, should be made relative or some reward, so sue.

That year, the event caused an uproar. Tokyo District Court presumed Nichia blue LED benefits obtained by up to 1,200 billion yen, Shuji Nakamura If the contribution of two to 50 percent calculation, should receive 60.4 billion yen of the price.

However, because of Shuji Nakamura, requires only 20 billion yen reward of gold, and, therefore, the court Nichia should pay 20 billion yen paid in full gold I Shuji Nakamura. However, Nichia first instance verdict appeal. The process dragged on for years, and finally in January 11, 2005, the two sides reached a settlement with 844 million yen, with industrial workers has also become a topic of patent litigation teaching.

Blue LED achievement

Shuji Nakamura then developed a LED when, in fact, there are many industry vendors are perplexing because they LED durability and reliability, far less than provided by Nichia LED. Other vendors until several years later, the only way to catch up with Nichia in white LED, blue LED achievement.

As of today, whether it is Apple iPad and iPhone products, or high-end Android phones panel screen uses LED backlighting chips, Nichia LED supply chain is still the first choice on the size, brightness, luminous efficiency and stability , LED backlight product quality Nichia's still better than most manufacturers.
