ABSTRACT:
Superconductivity occurring in 2-dimension has been understood in the framework of Kosterlitz-Thouless theory, and the nature of the transition is very different from that in 3-dimension. We present our recent data on superconducting properties of ultra-thin tantalum films, and compare with predictions based on the Kosterlitz-Thouless theory. Breakdown of superconductivity near the critical current and new findings on the phenomenon will also be discussed.
