Nanoscale substrate sculpting boosts superconductivity at higher temperatures, stronger magnetic fields
Researchers at Chalmers University of Technology in Sweden have reported a method to enhance superconductivity in ultrathin films by modifying the surface of the supporting substrate at the nanoscale. The advance, published June 17 in Nature Communications, allowed a copper-oxide superconductor to remain superconducting at higher temperatures and under stronger magnetic fields than previously possible, according to the study.
