Superconductors are dissipationless carriers of electric current and provide macroscopic, and thus robust, quantum coherence. To achieve the required performance employed in applications as magnetic sensors, nowadays bulk superconductors frequently need nanoscale engineering. Interestingly, when these materials are reduced to the nanoscale becoming nano-superconductors, novel exciting physical phenomena emerge. This has encouraged the study of their performance in the three dimensions as key elements that would be implemented into superconducting circuits. Nevertheless, the fabrication and characterization of nano-superconductors in the three dimensions are still challenging. Here, I introduce a direct-write nanolithography method based on focused ion beam technologies to fabricate at-will advanced nano-superconductors. Particularly, I have prepared superconducting W-C nanostructures in the three dimensions by decomposing tungsten hexacarbonyl molecules with a highly-focused He+ or Ga+ ion beam.
