C. Ciuhu, A. Lodder. Model calculations of the proximity effect in finite multilayers. Superlattices and Microstructures, 30, p. 95, 2001.

Abstract: The proximity-effect theory developed by Takahashi and Tachiki
for infinite superconductor/normal (S/N) multilayers is applied to
multilayer systems with a finite
number of layers in the growth direction. The purpose is to investigate
why previous applications to infinite multilayers fail to describe the
measured data satisfactorily.
It is shown that surface superconductivity may appear, depending
on the thickness of the covering normal metallic layers on both
the top and the bottom. Most of the parameters used refer
to the V/Ag system, but systems in which the N metal is also a
superconductor are considered as well. The nucleation process is
studied as a function of the system parameters, including the transparency
of the S/N interface.

Keywords: superconductivity, mesoscopic physics
