josephson effect


noun Electronics.

  1. a high-speed switch, used in experimental computers, that operates on the basis of a radiative phenomenon (Jo·sephson effect) exhibited by a pair of superconductors separated by a thin insulator.

noun

  1. 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

  1. 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).
