Hiroshi Amano (Japanese: 天野 浩, romanized: Amano Hiroshi; born September 11, 1960) is a Japanese electronics engineer specializing in the field of semiconductor technology. He is a co-inventor of the blue LED, for which he was awarded the 2014 Nobel Prize in Physics along with Isamu Akasaki and Shuji Nakamura.[1]

Early life and education

[edit]

Hiroshi Amano was born on September 11, 1960, in Hamamatsu, Japan, the son of father Tatsuji and mother Yoshiko.[2]

During elementary school days, Amano played soccer as a goalkeeper and softball as a catcher. He was also passionate about amateur radio and despite hating studying, he was good at mathematics. Upon entering high school, he began taking his studies seriously and became a top student by studying every day late into the night.

In 1979, Amano entered Nagoya University, where he received his B.E., M.E., and D.E. degrees in 1983, 1985, and 1989, respectively.[3]

Career

[edit]

From 1988 to 1992, Amano was a research associate at Nagoya University. In 1992, he moved to Meijo University as an assistant professor. From 1998 to 2002, he was an associate professor. In 2002, he became a professor. In 2010, Amano returned to Nagoya University, where he is currently a professor in the Graduate School of Engineering.[3]

Research

[edit]
Blue light-emitting diodes

Amano joined Professor Isamu Akasaki's group in 1982 as an undergraduate student. Since then, he has been doing research on the growth, characterization and device applications of group III nitride semiconductors, which are well known as materials used in blue light-emitting diodes today. In 1985, he developed low-temperature deposited buffer layers for the growth of group III nitride semiconductor films on a sapphire substrate, which led to the realization of group-III-nitride semiconductor based light-emitting diodes and laser diodes. In 1989, he succeeded in growing p-type GaN and fabricating a p-n-junction-type GaN-based UV/blue light-emitting diode for the first time in the world.

Known to be keen on research, Amano's laboratory was always lit late at night, such as weekdays, holidays, New Year's Day, and was called "no night castle".[4] According to his students in the laboratory, Amano has an optimistic and temperate personality, and is never angry.[5][6]

Family

Amano's wife is a Japanese lecturer at Comenius University in Bratislava, Slovakia.[7]
