摘要: We report on a controlled method to fabricate in-situ superconducting (SC) nanostructure at the apex of standard W tip Scanning Tunnelling Microscope (STM) by pulsing tunnelling voltage graphene covered metal surface. have characterized SC properties resulting as function temperature and magnetic field, obtaining transition 3.3 K critical field well above 3T. The nanotip is robust, stable, achieves atomic resolution. non-SC can be easily recovered clean present result should taken into account when studying zero-bias features like Kondo resonances or superconductivity graphene-based systems means STM using tungsten tips.
