Second generation high-temperature superconducting (2G-HTS) tape and fabrication method thereof

A method for fabricating a second generation high-temperature superconductor (2G-HTS) tape, comprising:

• (S1) depositing a first superconducting film on a surface of a ductile metal substrate, wherein the ductile metal substrate is provided with a buffer layer;
• (S2) forming a micro-holes array pattern on a surface of the first superconducting film by etching using a reel-to-reel dynamic femtosecond infrared laser etching system, wherein the micro-holes array pattern covers the first superconducting film;
• (S3) depositing a second superconducting film on the surface of the first superconducting film, wherein a thickness of the second superconducting film is larger than that of the first superconducting film;
• and
• (S4) depositing a silver protective layer and a copper stabilization layer on a surface of the second superconducting film to fabricate the 2G-HTS tape.
