the gap structure and pairing symmetry have not so far been determined. Here we report scanning tunnelling spectroscopy of Nb superconducting films proximity coupled to epitaxial Ho. These ...

Finding confirms that electron pairing in these high-temperature, high-pressure superconductors is mediated by phonons ...

This indicates that the parts of the Fermi surface remain ungapped deep in the superconducting state. Eventually a gap opens ...

The world's first Nb 3 Sn superconducting radio-frequency (SRF) electron accelerator recently achieved stable beam acceleration, reaching a maximum energy of 4.6 MeV with an average macro-pulse ...

The key to understanding superconductivity lies in the superconducting gap – a fundamental property that reveals how electrons pair up to form the superconducting state. It is the identification ...

Using electron tunneling spectroscopy under high pressure, the international research team led by the Max Planck Institute for Chemistry has measured the superconducting gap of H 3 S—the ...

The study revealed that the size of the superconducting gap and the sharpness of coherence peaks exhibit periodic spatial modulations with the same period of the crystal lattice. Crucially ...
