Robust, switchable, C-related, Superconducting Nanostructure at the Apex of a W tip

C. G. AYani, F. Calleja, P. Casado +8

We report on a controlled method to fabricate in-situ a superconducting (SC) nanostructure at the apex of the standard W tip of a Scanning Tunnelling Microscope (STM) by pulsing th…
