Description
Munisa A Tomayeva and co-authors show that the curve of a metal-superconductor border steers how far the superconducting state leaks into normal metal. That leak, the proximity effect, fades with distance at a pace set by temperature and dimension. Hybrid devices live or die by its reach.
At low heat the fade follows a power law, not the swift drop seen warmer. The team proves that border curvature rewrites the law's exponent. Inward curves stretch the leak's reach; outward curves pinch it. Border shape also sets how cleanly pairs cross the junction in the first place. Both effects hand device builders a geometry dial for tuning hybrids. Sensors and quantum circuits built on such junctions gain design room.
