TOKYO & MENLO PARK, Calif., Sept. 18 -- Isamu Akasaki and Hiroshi Amano, both of Meijo University, and Shuji Nakamura of the University of California, Santa Barbara, will share an $833,000 Takeda Award for their work on blue light-emitting semiconductor devices. The annual award by the Takeda Foundation, to be presented Nov. 20 in Tokyo, was established last year to recognize those who have made outstanding achievements in information and electronics, the life sciences and the environment. Akasaki, Amano and Nakamura will receive the information and electronics category award.
