Three scientists, including the Father of LED Blue light, won the 2014 Nobel Prize in Physics


Phoenix Science and Technology News October 7 News: Nobel Prize in physics was announced at Beijing time at 5:45 on October 7, Akasaki , Hiroshi Amano and Shuji Nakamura awards. Isamu Akasaki and Hiroshi Amano are Japanese scientists and Shuji Nakamur is a U.S. citizen.


  Official announcement of the winning reasons:

  The three winners made a significant contribution to the discovery of a new and highly efficient, environmentally friendly light source, the Blue Light Emitting Diode (LED). With the help of a blue LED, white light can be created in new ways. With LED lights, we can have more durable and more efficient lighting to replace the original light source.

  In the mid-1990s, ultra-large-screen full-color displays that exceeded the height of human beings were made possible. In the mid-2000s, high-brightness blue LEDs were also contributed to the screen colorization of mobile phones. Blue LED technology has also become the basis for the development of blue lasers, in fact making it possible to record Blu-ray for HD programming. High-brightness blue LEDs can be made in a variety of colors by combining them with red and green LEDs, followed by a huge market for a new generation of energy-efficient lights that will replace incandescent and fluorescent lamps.

  Japanese companies and universities have made a significant contribution to the development of high-brightness blue LEDs. In the research stage of GaN LED, Professor Akasaki Nagasaki of Nagoya University (now Distinguished Professor of City University) and Amano Akihiro have made outstanding achievements. In the later practical and high brightness stage, Nichia Nakamura of Nichia (now a professor at the University of California, Santa Barbara) played an important role.

  Stories of Nakamura Shuji:

  Nakamura Shuji, who made outstanding contributions to the practical use of blue LEDs, did not get any remuneration from Nichia at first because Nichia Chemical forbade employees from publishing papers. Therefore, during the study period, The company secretly published in foreign journals, because he did not publish influential papers in Japan, which led to Shuji Nakamura's resignation from Nichia, and even could not find a willing to accept their own businesses or research institutes. In desperation, Shuji Nakamura in 2000 to the University of California, Santa Barbara.

  Nichia received a billions of dollars in profits from the patent of Shuji Nakamura and from there a small but unknown company grew into a giant in the industry. Shuji Nakamura sued Nichia in 2001 and eventually ruled Nichia Pay 20 billion yen (about 182 million US dollars), so Shuji Nakamura may be the richest Nobel Laureate ever.
