Such nanosuperconductors are being investigated for potential applications in nanoelectronics and quantum computing. The design of three-dimensional nanosuperconductors allows one to conceive novel schemes for such applications. Here, we report for the first time the use of a He+ focused-ion-beam-microscope in combination with the W(CO)6 precursor to grow three-dimensional superconducting hollow nanowires as small as 32 nm in diameter and with an aspect ratio (length/diameter) of as much as 200. Such extreme resolution is achieved by using a small He+ beam spot of 1 nm for the growth of the nanowires. As shown by transmission electron microscopy, they display grains of large size fitting with face-centered cubic WC1-x phase. The nanowires, which are grown vertically to the substrate, are felled on the substrate by means of a nanomanipulator for their electrical characterization. They become superconducting at 6.4 K and show large critical magnetic field and critical current density resulting from their quasi-one-dimensional superconducting character. These results pave the way for future nanoelectronic devices based on three-dimensional nanosuperconductors. 000076897 536__ $$9info:eu-repo/grantAgreement/ES/MINECO/MAT2014-51982-C2-2-R$$9info:eu-repo/grantAgreement/ES/MINECO/MAT2014-51982-C2-1-R$$9This project has received funding from the European Union’s Horizon 2020 research and innovation program under grant agreement No H2020 654360-NFFA-Europe$$9info:eu-repo/grantAgreement/EC/H2020/654360/EU/NANOSCIENCE FOUNDRIES AND FINE ANALYSIS - EUROPE/NFFA-Europe$$9info:eu-repo/grantAgreement/ES/DGA/E81$$9info:eu-repo/grantAgreement/ES/DGA/E26 000076897 540__ $$9info:eu-repo/semantics/openAccess$$aAll rights reserved$$uhttp://www.europeana.eu/rights/rr-f/ 000076897 590__ $$a12.279$$b2018 000076897 591__ $$aCHEMISTRY, PHYSICAL$$b10 / 148 = 0.068$$c2018$$dQ1$$eT1 000076897 591__ $$aMATERIALS SCIENCE, MULTIDISCIPLINARY$$b19 / 293 = 0.065$$c2018$$dQ1$$eT1 000076897 591__ $$aNANOSCIENCE & NANOTECHNOLOGY$$b10 / 94 = 0.106$$c2018$$dQ1$$eT1 000076897 591__ $$aPHYSICS, CONDENSED MATTER$$b8 / 68 = 0.118$$c2018$$dQ1$$eT1 000076897 591__ $$aCHEMISTRY, MULTIDISCIPLINARY$$b16 / 172 = 0.093$$c2018$$dQ1$$eT1 000076897 591__ $$aPHYSICS, APPLIED$$b9 / 148 = 0.061$$c2018$$dQ1$$eT1 000076897 592__ $$a6.211$$b2018 000076897 593__ $$aBioengineering$$c2018$$dQ1 000076897 593__ $$aChemistry (miscellaneous)$$c2018$$dQ1 000076897 593__ $$aNanoscience and Nanotechnology$$c2018$$dQ1 000076897 593__ $$aMaterials Science (miscellaneous)$$c2018$$dQ1 000076897 593__ $$aMechanical Engineering$$c2018$$dQ1 000076897 593__ $$aCondensed Matter Physics$$c2018$$dQ1 000076897 655_4 $$ainfo:eu-repo/semantics/article$$vinfo:eu-repo/semantics/acceptedVersion 000076897 700__ $$0(orcid)0000-0002-4599-3013$$aIbarra, A.$$uUniversidad de Zaragoza 000076897 700__ $$aMailly, D. 000076897 700__ $$0(orcid)0000-0001-9566-0738$$aDe Teresa, J.M.$$uUniversidad de Zaragoza 000076897 7102_ $$12003$$2395$$aUniversidad de Zaragoza$$bDpto.
