Abstract
Quantum confinement of electrons in clean nanowires and nanofilms results in the formation of a series of subbands that move in energy with changing wire/film thickness. When the bottom of such a subband moves through the Fermi surface, the density of states changes and a size-dependent superconducting resonance appears, leading to quantum-size oscillations in the critical temperature Tc and the order parameter 4 . Our theoretical formulation is based on a numerical solution of the Bogoliubovde Gennes equations in the clean limit.
