Esaki was awarded the Nobel Prize for Physics in 1973 for this early discovery of the tunnelling phenomenon in semiconductors and superconductors.
Esaki, born in Osaka, graduated from the University of Tokyo and worked for electronics manufacturer Sony 1956–60.
Esaki was able to use this effect for switching and to build ultrasmall and ultrafast tunnel diodes, now called Esaki diodes.

Esaki was a 1947 graduate in physics from Tokyo University and immediately joined the Kobe Kogyo company.
Esaki's work at Sony was in the field of quantum mechanics and concentrated on the phenomenon of tunneling, in which the wavelike character of matter enables electrons to pass through barriers that the laws of classical mechanics say are impenetrable.
In 1960 Esaki was awarded an IBM (International Business Machines) fellowship for further research in the United States, and he subsequently joined IBM's research laboratories in Yorktown, N.Y. He retained his Japanese citizenship.

Leo Esaki proposed in 1969 the concept of semiconductor "superlattice," man-made single-crystal with a periodic one-dimensional structural modification.
Esaki's conception of superlattice has thus led to the discovery of many interesting new properties -electrical, optical, and magnetic- and their useful applications, which makes him well deserve the 1998 Japan Prize in the category of "Generation and Design of New Materials Creating Novel Functions."
