摘要

Researchers at Oak Ridge National Laboratory (ORNL) have combined theoretical and experimental studies to understand and control the self-assembly of insulating barium zirconium oxide nanodots and nanorods within barium-copper-oxide superconducting films. The lead researcher on the project, Amit Goyal, says: "We found that a strain field that develops around the embedded nanodots and nanorods is a key driving force in the self-assembly. By tuning the strain field, the nanodefects self-assembled within the superconducting film and included defects aligned in both vertical and horizontal directions."
