3 Nobel prize winners lecture in Stockholm
The 3 winners of this year's Nobel Prize in Physics delivered speeches in Sweden on Monday ahead of the award ceremony.
Professor Isamu Akasaki of Meijo University was the first lecturer at the annual Nobel Lecture event at a university in Stockholm.
Akasaki appeared on the podium wearing a blue necktie, saying he would talk about a blue light.
Akasaki referred to the successful creation of the gallium nitride crystal, which led to the blue LED. He said he recognized the possibility of the crystallized material becoming the blue LED when he was looking at it through a microscope.
Akasaki said his co-researcher Hiroshi Amano's tenacious efforts contributed to creating the ideal crystal. He described the moment he saw the blue light as the most memorable event in his life in research.
Professor Hiroshi Amano of Nagoya University Graduate School was the second to take the podium. Amano said he started his research with the idea that the blue LED would change TV display screens, but he was not aware that it would be such a difficult subject.
Amano recalled the successful creation of a high-quality gallium nitride crystal, which is needed to create blue light. He said the development came accidentally when an old device failed to raise the temperature to the expected level. He also said the sample was so perfectly transparent that he thought it was unsuccessful. He added that he was sure that it was the crystal he had been seeking when he saw it through a microscope.
As advice to young people, Amano said he wants them to take on challenges and contribute to humankind.
The 3rd speaker was Professor Shuji Nakamura of the University of California, Santa Barbara. Nakamura said there were not many researchers who used gallium nitride to develop the blue LED.
He added that he remembers that only three people -- himself, Akasaki and Amano -- attended an academic conference on the topic in Japan.
