摘要：

The transition temperature of clean superconducting superlattice is shown to be raised above that of bulk superconductor, by choosing material parameters properly. This is due to the interference of the wave function which is reflected by the multilayered structure. However we can not expect this effect in the superconducting superlattice in the dirty limit, as the wave character of the Cooper pair is smeared out due to the impurity scattering.
