He is one of only three Japanese physicists ever to receive the Nobel Prize. Interestingly enough, all three attended the Third High School (equivalent to the present junior college) in Kyoto, which may be no more than just coincidence or proof of the importance of an educational environment in developing scientific talent. Esaki went on to major in physics at the University of Tokyo because he wanted to understand nature in a most fundamental way, but credits the war-time psychology as also having an effect on him, especially after the war. It was then that he decided to go into industrial research, in order to participate more effectively in the process of rebuilding war-torn Japan. He joined Sony Corporation, and it was there in 1957 that he discovered the tunnel diode, the first quantum electron device, for which he received a Ph.D. in physics and, later, the 1973 Nobel Prize in physics.

Esaki, Leo Japanese physicist who in 1957 noticed that electrons could sometimes 'tunnel' through the barrier formed at the junctions of certain semiconductors. The effect is now widely used in the electronics industry. For this early discovery Esaki shared the 1973 Nobel Prize for Physics with British physicist Brian Josephson and Norwegian-born US physicist Ivar Giaever Esaki, born in Osaka, graduated from the University of Tokyo and worked for electronics manufacturer Sony 1956-60. He then joined IBM's research centre in Yorktown Heights, New York, but returned to Japan 1992 as president of the University of Tsukuba. Tunnelling is a quantum-mechanical effect whereby electrons can travel through electrostatic potentials that they would be unable to overcome classically. Esaki was able to use this effect for switching and to build ultrasmall and ultrafast tunnel diodes, now called Esaki diodes. He continued to research the nonlinear transport and optical properties of semiconductors, in particular multilayer superlattice structures grown by molecular-beam epitaxy techniques.

Esaki, Leo Japonský fyzik pevné fáze a výzkumník supravodivosti, který dostal spolu s Ivarem Giaeverem a Brianem Josephsonem Nobelovu cenu za fyziku pro rok 1973 za experimentální objev tunelového jevu v polovodièích a supravodièích. Jeho pùvodní jméno je Esaki Reiona. V roce 1947 Esaki vystudoval Tokijskou universitu a stal se zamìstnancem spoleènosti Kobe Kogyo. V roce 1956 se stal hlavním fyzikem spoleènosti Sony, kde provádìl experimenty, které posléze vedly k udìlení Nobelovy ceny. V roce 1959 získal na rodné universitì titul PhD. Esakiho práce ve spoleènosti Sony se ubírala smìrem ke kvantové mechanice a zejména k tunelovému jevu, pøi kterém vlnový charakter hmoty dovolí elektronùm pøekroèit energetickou bariéru, která by v klasické mechanice byla neprostupná. Navrhl, jak by bylo možné pozmìnit chování polovodièù z pevných látek pøidáním pøímìsí (dopantù). Tato práce vedla k jeho vynálezu - dvojdiody, která je také známá pod názvem Esakiho dioda . V roce 1960 byla Esakimu udìlena cena spoleènosti IBM (International Business Machines) za výzkum. Hned poté se stal jejím zamìstnancem a zaèal pracovat ve výzkumných laboratoøích v Yorktown ve státì New York. V USA si ponechal japonskou státní pøíslušnost.

Dr. Esaki, Leo (Japan) (President, University of Tsukuba) Prize Category: Generation and Design of New Materials Creating Novel Functions Reasons for Award: For the creation and realization of the concept of man-made superlattice crystals which lead to generation of new materials with useful applications Dr. Leo Esaki Dr. Leo Esaki proposed in 1969 the concept of semiconductor "superlattice," man-made single-crystal with a periodic one-dimensional structural modification. He predicted that a superlattice would exhibit peculiar properties such as negative differential conductivity because the density of states has a short-period modulation in the k-space. He proposed to realize a superlattice by modulating either alloy composition or impurity density during thin-film crystal growth. His efforts on molecular-beam epitaxy paid off in 1972 when he discovered a negative differential conductivity in a GaAlAs superlattice. He also predicted a resonant tunneling phenomenon between adjacent potential wells in a superlattice, and confirmed it experimentally in 1973. Dr. Esaki's work on superlattice had a tremendous influence on other scientists. Firstly, he suggested the concept of modulation doping (overflow of conduction electrons or holes that originate from impurities in a wide-bandgap region into a narrow-bandgap region). The HEMT, a high-speed field effect transistor, was developed in 1980 based on this concept, and is now widely used in wireless telecommunications. Secondly, semiconductor lasers and photo-detectors with superlattice (or multiple-quantum-well as it is often called) structures were invented during the 1980's and are now very important components in optical communications. Thirdly, GMR (Giant Magneto-Resistance) was discovered in the late 1980's in a superlattice structure consisting of magnetic and non-magnetic metals and are being pursued as sensors for magnetic recording.
