 Superconductive Sandwiches? Josephson Junctions, SQUIDs, and the Voltage Standard

If you make certain materials extremely cold, they no longer have any resistance. This can result in strange and interesting effects. But how can we use these effects? One way is to make a Josephson junction – a superconducting sandwich consisting of a thin layer of non-superconducting material between two superconductors. We can use these junctions as circuit elements, with applications from defining a volt to measuring the strength of a magnetic field. We will cover these applications, as well as the process of fabricating the junctions themselves!
