Esaki Leo (született: Esaki Reona, japánul: 江崎 玲於奈) ( Oszaka, 1925. március 12. –) japán fizikus, 1973 -ban Ivan Giaeverrel és Brian Josephsonnal megosztva kapta meg a fizikai Nobel-díjat. A szilárdtestek és a szupravezetés vizsgálatával foglalkozik.
Leo Esaki was born in 1925 in Osaka, Japan. He studied physics at the University of Tokyo, and decided to engage in industrial research in order to help rebuild post-war Japan. He took at position at 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 Ballantine Medal from ...
18 de may. de 2018 · Leo Esaki. Leo Esaki (born 1925) was one of three winners of the Nobel Prize in Physics in 1973. Esaki was honored for his 1957 pioneering work in electron tunneling in semiconducting materials, which led to his creation of the Esaki diode, or tunnel diode. This technology helped advance research in optical and wireless communication devices.
Reona Esaki (江崎 玲於奈 Esaki Reona, born March 12, 1925), also known as Leo Esaki, is a Japanese physicist. He was awarded the Nobel Prize in Physics in 1973 with Ivar Giaever and Brian David Josephson.
Leo Esaki. 1925-. Japanese physicist whose research into quantum mechanical tunneling won the 1973 Nobel Prize for Physics. Tunneling, the process by which electrons (and other particles) can "escape" from an atom, has been used most recently in the scanning tunneling microscope, which can provide atomic-scale "images" of surfaces. In addition ...
In the late 1950's, Dr. ESAKI discovered a characteristic called negative resistance whereby, for PN junction diodes with a large amount of impurities added, the current decreases with increasing voltage, and confirmed that this phenomenon is due to the quantum mechanical tunneling effect of electrons.
The Nobel Prize in Physics 1973 was divided, one half jointly to Leo Esaki and Ivar Giaever "for their experimental discoveries regarding tunneling phenomena in semiconductors and superconductors, respectively" and the other half to Brian David Josephson "for his theoretical predictions of the properties of a supercurrent through a tunnel barrier, in particular those phenomena which are ...
