STANDARD MANUFACTURE AND PROPERTIES OF ARRAYS OF Pb AND Sn NANOWIRES

Nanowires grown by electrodeposition using nanoporous template have attracted much attention due to the simplicity of this technique for preparing nano-scaled materials. We present here a standard way to fabricate lead or tin nanowire arrays. We also present some of their superconducting properties directly affected by the reduced dimensions; these are the magnetic flux penetration and confinement in nanowires having a diameter only a few times the magnetic penetration length, as well as the formation of phase-slips centres in nanowires having a diameter smaller than the coherence length.
