Granularity and superconductor-insulator transition in electrochemically anodized Al films
We report the use of an electrochemical anodization process to fabricate ultrathin granular Al films at room temperature. These films display a superconductor-insulator transition of the same character as those found in quench-condensed granular films. The granularity of the films and the unusually narrow distribution of the grain sizes are shown by scanning force microscopy.
