Tokyo, Oct. 26 (Jiji Press)--Junichi Nishizawa, former president of Tohoku University and a world authority on optical communication and semiconductors, died on Sunday, the university said Friday. He was 92.

A native of the northeastern Japan city of Sendai, Miyagi Prefecture, Nishizawa started studying transistors at graduate school after finishing his undergraduate degree at the university's School of Engineering in 1948.

He invented the PIN diode, the static induction transistor and other groundbreaking devices from the 1950s onward.

A pioneer of the semiconductor field, he was nicknamed "Mr. Semiconductor."

Nishizawa was one of the earliest people to focus on the potential of optical communication technology.
