1. Introduction to Superconductivity

8. At T <Tc interesting steps appear in the IVCs : the existence of constrictions in the width and/or thickness of the stripe forces the current to exceed Ic in the constrictions first, and the superconducting order parameter collapses. Analysis of IVCs of nanostripes IV characteristics of the nanostrip at T=6.6 K (left) and T=7K (right) Line widths 150nm-800nm N=6 series of M=3 parallel Nanostripes parallel Nanostripes

9. The steps are much more in an intermediate region (T BKT <T<T ph ) ???? a linear behaviour of Ic(T) 400nm NbN(8)/NiCu(5) Analysis of IVCs of nanostripes
