Leona Esaki also known as Leo Esaki (江崎 玲於奈 Esaki Reona, born March 12, 1925) is a Japanese physicist who shared the Nobel Prize in Physics in 1973 with Ivar Giaever and Brian David Josephson for his discovery of the phenomenon of electron tunneling. He is known for his invention of the Esaki diode, which exploited that phenomenon. This research was done when he was with Tokyo Tsushin Kogyo (now known as Sony). He has also contributed as a pioneer of semiconductor superlattice while he was with IBM.
Subsequently, he served as the President of various Japanese universities, for example, University of Tsukuba. Since 2006, he is serving as the President of the Yokohama College of Pharmacy.
Esaki is the recipient of The International Center in New York's Award of Excellence.
