Summary
Chalmers researchers reported that nanoscale sculpting of the substrate beneath an ultrathin cuprate film kept it superconducting at higher temperatures and under stronger magnetic fields.
A high-temperature vacuum treatment created ordered ridges and valleys on the substrate, which guided atomic arrangement at the interface and stabilized the superconducting state.
The team used YBa2Cu3O7−δ films only a few nanometers thick, showing performance gains without changing the material’s chemistry—an alternative to years of limited composition-based progress.
The result, published in Nature Communications, points to a broader design rule for superconductors that could aid energy-efficient electronics, quantum devices and systems operating in magnetic-field-heavy environments.
That matters because digital devices, data centers and ICT networks already consume an estimated 6% to 12% of global electricity, while many superconductors still require cooling near minus 200C.
This new method makes superconductors stronger, but can it be scaled to build the practical quantum computers of tomorrow?
With multiple breakthroughs emerging, which new superconductor technology will win the race to revolutionize energy and computing?
Can sculpting surfaces at the nanoscale truly solve the massive energy crisis driven by AI and data centers?
