Ultra-thin superconductors from a single atomic layer are considered as key materials for more compact quantum devices. Their big problem is that they decompose in air within minutes. Researchers: within MIT have now developed a method that removes this obstacle and allows for the first time large-scale, air-stable layers of the superconductor niobium diselenide. The work could pave the way to significantly more compact superconducting quantum c…
