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)
