Investigation of defects in functional layer of high temperature superconducting tapes.

Highlights: [•] We found correlation between structure and electric properties in HTS tapes. [•] The outgrowths of various morphologies were observed in the (RE)BCO layers. [•] The outgrowths at the tape edges have higher distribution density than in the center. [•] The outgrowths influence the crystal orientation of adjacent (RE)BCO grains. [ABSTRACT FROM AUTHOR]
