Zero Resistivity in superconductors

  1. Jul 14, 2010 #1
    What is the meaning of zero resistivity in superconductors? I mean, what's the cause of zero resistivity in superconductors?

    There is no resistance, so currents will flow indefinitely. The cause is lowering the superconductor below its critical temperature (T_c). Usually liquid helium or nitrogen is used to cool a superconductor below T_c.

    Title should be "superconconductor", not "semi-".

    Title has been changed.

    A nice explanation by nobel laureate Leggett can be found here:

    Very readable is also the article by Brun Hansen, "Infinite conductivity of ordinary and gapless superconductors", Physica, Vol 39, p. 271-292, (1968)
