Josephson effect

   Also found in: Encyclopedia, Wikipedia, Hutchinson 0.06 sec.
Jo·seph·son effect  (jzf-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  (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).
