For what invention did Professor Shuji Nakamura, the 2014 Nobel Prize winner in Physics, win the Nobel Prize?

He won the 2014 Nobel Prize in Physics for the invention of the "high-efficiency blue light-emitting diode".

Shuji Nakamura was born on May 22, 1954 in Ikata, Japan. He graduated from Tokushima University, Japan. He is a Japanese-American electronic engineer and a graduate of the University of California, Santa Barbara. Professor in the Department of Materials, School of Engineering.

Nakamura Shuji became well-known for developing high-brightness blue LEDs based on GaN in 1993 while working at Nichia Corporation in Japan. At the time, developing a blue LED was considered impossible, as only red and green LEDs had been available for the previous 20 years.

Shuji Nakamura, who won the 2014 Nobel Prize in Physics for developing blue-light LEDs, held a press conference at the Foreign Correspondents' Association in Japan in Tokyo on January 16, 2015, criticizing Japan's patent system and the entire East Asian education systems. He criticized Japan's education system, saying that the university entrance examination system is very bad, as is the case in China and South Korea. The educational goal of all high school students is to be admitted to famous universities.
