“…Since there is no report available on the penetration depth of In nanowires, we tried to get an approximate estimate of the same from the existing reports on thin films and nanoparticles of In. The penetration depth of a thin In film ͑of ϳ100 nm thickness͒ was reported 19 to be 39 nm at absolute zero. This value is much larger than the bulk penetration depth ͑25 nm as determined by ultrasonic attenuation measurements 20 ͒ and the penetration depth reported for In nanoparticles ͑3.3 nm͒.…”

We have synthesized indium (In) nanowires in pure form and large scale, encapsulated within insulating ZnS nanotubes, and examined the intrinsic superconductivity in one-dimensional limit. We demonstrate that the property of the superconducting nanowires encapsulated within insulating nanotubes can be controlled down to diameters much smaller than the characteristic lengths. The critical temperature and critical magnetic field of the one-dimensional In nanowires are not affected down to a diameter of 40 nm, almost 10% of the coherence length of bulk In. This study further suggests that superconducting interconnects, with controlled physical properties, in nanocircuits could be achieved by such encapsulation.
