Leo Esaki - Elctron Tunnelling

Synopsis
Leo Esaki is a Japanese physicist who shared half the Nobel Prize in Physics in 1973 with Ivar Giaever for the discovery of the phenomenon of electron tunnelling. The second half of the prize was awarded to Brian David Josephson. He is known for his invention of the Esaki diode, which exploited the electron tunnelling phenomenon. In this interview, recorded in 2004, Esaki tells he graduated in 1947, which was a difficult time for Japan, and he decided to go into industry to try contribute to the economy through working in electronics. The company that he worked for later developed into Sony.

His early work was on the vacuum tube which was the dominant electronic device prior to 1947 when the transistor was invented at Bell Telephone and the new fiield of semiconductor physics was born. Leo Esaki is both an experimentalist and a theoretician. (8 minutes)

Notes
Well-established maker and distributor of more than 200 programmes on science, technology, engineering and mathematics, many of which have been broadcast. Vega’s videos aim to give a fundamental understanding of principles of nature and the physical world. Outstanding scientists/communicators are directly involved with each video so that they can guide content of the programmes. Science is presented in a natural way as an intellectually challenging discipline and the videos fill the gap in TV coverage by presenting well-informed analyses on serious science-related ethical, economic, social, health and other issues. Separate series consist of interviews with eminent scientists, science video lectures, issues of current scientific concern, the Royal Institution Discourses, scientific masterclasses, and recent research projects. Programmes available for free viewing via the website and some also for sale on DVD.
