Hiroshi Amano, a Japanese physicist and engineer, achieved international recognition for his pivotal role in developing blue light-emitting diodes. Born in Hamamatsu on September 11, 1960, he dedicated his career to advancing semiconductor technology. His breakthroughs in group III nitride semiconductors provided the technical foundation for modern high-efficiency lighting and electronic displays used globally today.
Academic Foundations
Amano completed his early education at Hamamatsu City Shijimizuka Junior High School and Shizuoka Prefectural Hamamatsu Nishi High School. He entered Nagoya University in 1979, graduating from the School of Engineering in 1983. He continued his studies at the same institution, finishing his master’s degree in 1985 and earning his Doctor of Engineering degree in 1989.

Beginning in 1982, Amano joined the laboratory of Isamu Akasaki at Nagoya University. His work focused on the growth and characterization of group III nitride semiconductors. In 1985, he created low-temperature buffer layers for growing these films on sapphire substrates. By 1989, he successfully grew p-type GaN, which enabled the fabrication of the first p-n-junction-type GaN-based ultraviolet and blue light-emitting diodes.
Professional Career
Amano served as a research associate at Nagoya University from 1988 to 1992. He subsequently moved to Meijo University, holding assistant, associate, and full professor roles between 1992 and 2010. He returned to Nagoya University in 2010 to serve as a professor in the Graduate School of Engineering and has directed the Akasaki Research Center since 2011.
Scientific Recognition
In 2014, Amano received the Nobel Prize in Physics alongside Isamu Akasaki and Shuji Nakamura for their collective contributions to energy-efficient blue light sources. During the same year, the Japanese government granted him the Order of Culture and designated him a Person of Cultural Merit. He also holds an honorary doctorate from the University of Padua.
