Proximity effects

Proximity effect is a phenomenon that occurs when a non-superconducting metal is in relatively `clean` electric contact with a superconductor – a weak sign of superconductivity is shown in the normal metal.

This is known for many years – our focus is to try and see if we can see those effects across the entire SIT (superconductor to insulator transition) – especially in the insulator side. First results have kept us optimistic as we saw superconductivity in Ag (silver) when a thin layer of Pb (lead) has been deposited on top of it. Our goal is to continue and study this phenomenon in both those materials and compare the results to a bit more `exotic` materials – for example InO that is believed to have `electrical granularity`
