Vertical Growth of Superconducting Crystalline Hollow Nanowires by He+ Focused Ion Beam Induced Deposition 2018 Access copy available to the general public Unrestricted Novel physical properties appear when the size of a superconductor is reduced to the nanoscale, in the range of its superconducting coherence length (¿0). 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. info:eu-repo/grantAgreement/ES/MINECO/MAT2014-51982-C2-2-R info:eu-repo/grantAgreement/ES/MINECO/MAT2014-51982-C2-1-R This project has received funding from the European Union’s Horizon 2020 research and innovation program under grant agreement No H2020 654360-NFFA-Europe info:eu-repo/grantAgreement/EC/H2020/654360/EU/NANOSCIENCE FOUNDRIES AND FINE ANALYSIS - EUROPE/NFFA-Europe info:eu-repo/grantAgreement/ES/DGA/E81 info:eu-repo/grantAgreement/ES/DGA/E26 info:eu-repo/semantics/openAccess All rights reserved http://www.europeana.eu/rights/rr-f/ 12.279 2018 CHEMISTRY, PHYSICAL 10 / 148 = 0.068 2018 Q1 T1 MATERIALS SCIENCE, MULTIDISCIPLINARY 19 / 293 = 0.065 2018 Q1 T1 NANOSCIENCE & NANOTECHNOLOGY 10 / 94 = 0.106 2018 Q1 T1 PHYSICS, CONDENSED MATTER 8 / 68 = 0.118 2018 Q1 T1 CHEMISTRY, MULTIDISCIPLINARY 16 / 172 = 0.093 2018 Q1 T1 PHYSICS, APPLIED 9 / 148 = 0.061 2018 Q1 T1 6.211 2018 Bioengineering 2018 Q1 Chemistry (miscellaneous) 2018 Q1 Nanoscience and Nanotechnology 2018 Q1 Materials Science (miscellaneous) 2018 Q1 Mechanical Engineering 2018 Q1 Condensed Matter Physics 2018 Q1 info:eu-repo/semantics/article info:eu-repo/semantics/acceptedVersion (orcid)0000-0002-4599-3013 Ibarra, A.
