Jo·seph·son effect (j  z f-sn, -sf-)n. The effect associated with the tunneling of electron pairs across an insulating barrier separating two superconductors. [After Brian David Josephson (born 1940), British physicist.] |
Josephson effect [ˈdʒəʊzɪfsən]
n
(Physics / General Physics) Physics any one of the phenomena which occur when an electric current passes through a very thin insulating layer between two superconducting substances. The applications include the very precise standardization of the volt
[named after Brian David Josephson (born 1940), English physicist; shared the Nobel prize for physics in 1973]
| Josephson effect (jzf-sn) An effect in which electron pairs undergo quantum tunneling with zero resistance across a barrier separating two superconductors. The effect can be manipulated by varying a magnetic field at the junction where the tunneling occurs and is being investigated as a possible part of the design of high-speed switches for computer microprocessors. The Josephson effect is named after its discoverer, Welsh physicist Brian David Josephson (b. 1940). |
