Abstract:

We report measurements on two-dimensional arrays of Josephson junctions with junction sizes down to 60 nm by 60nm. Due to their small size, these junctions belong to the class of mesoscopic systems they show behavior which reveals the underlying quantum mechanical properties. Two energies characterize the junctions, the Josephson energy E sub j and the charging energy E sub c. Arrays in which E sub j E sub c are superconducting around zero bias and at zero temperature, while arrays in which E sub c E sub j, called charging arrays, are instead insulating. This is the basis of the superconductor-to-insulator S-I transition Author
