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". According to his students in the laboratory, Amano has an optimistic and temperate personality, and is never angry. == Family ==
