Nobel Prize in Physics.

The 7th, the Royal Swedish Academy of Sciences Professor Nakamura Isamu Akasaki Meijo tenured professor, Hiroshi Amano, Nagoya University professor, of the United States University of California at Santa Barbara, which was developed blue-light-emitting diode (LED), the Nobel Prize in Physics in 2014 it has announced it will award to Mr. 3. Achievement to contribute to the practical application of LED there are advantages such as long life with low power consumption, was popular as a next-generation light source has been evaluated.
In winning followed Mr. Shinya Yamanaka of '12 in (Physiology or Medicine Prize), Nobel Prize of Japanese a total of 22 people, including Mr. Yoichiro Nambu of the United States nationality. Prize in Physics was awarded second only southern Mr. '08, Makoto Kobayashi, Toshihide Maskawa to Mr..
The LED semiconductor devices that emit light efficiently by conducting electricity. High brightness LED red, green had been made ​​at an early stage, but the blue LED shorter wavelength, the development of technology for practical use had been referred to as "difficult during the 20th century." It is awarded after a long time. I am happy for you


スウェーデン王立科学アカデミーは７日、２０１４年のノーベル物理学賞を、青色発光ダイオード（ＬＥＤ）を開発した赤崎勇・名城大終身教授、天野浩・名古屋大教授、米カリフォルニア大サンタバーバラ校の中村修二教授の３氏に授与すると発表した。低消費電力で長寿命などの利点があるＬＥＤの実用化に貢献し、次世代の光源として普及させた功績が評価された。
　日本人のノーベル賞は１２年の山中伸弥氏（医学・生理学賞）に続く受賞で、米国籍の南部陽一郎氏を含め計２２人に。物理学賞は０８年の南部氏、小林誠氏、益川敏英氏に次ぐ受賞となった。
　ＬＥＤは電気を通すことで効率よく発光する半導体素子。赤色、緑色の高輝度ＬＥＤは早い段階で作られていたが、波長がより短い青色ＬＥＤは、実用に耐える技術の開発は「２０世紀中は困難」といわれていた。久しぶりの受賞ですね。良かったですね。
