Physica E: Low-Dimensional Systems and Nanostructures
We have experimentally studied the superconducting behavior of one-dimensional aluminum wires of various lengths. Each wire had much wider two-dimensional contact pads on both sides. At a temperature T below Tc, when the wide pads are driven normal by a perpendicular magnetic field, only samples longer than a critical length, Lcπξ(T), show evidence for superconductivity. This is a direct confirmation of the prediction by Liniger for a normal-metal-superconductor-normal-metal structure with clean interfaces. © 1994 The American Physical Society.
