NbSi nanowire quantum-phase-slip circuits: dc supercurrent blockade, microwave measurements and thermal analysis
C. H. Webster, J. C. Fenton, T. T. Hongisto +3
We present a detailed report of microwave irradiation of ultra-narrow superconducting nanowires. In our nanofabricated circuits containing a superconducting NbSi nanowire, a dc blo…
Quantum phase slip phenomenon in ultra-narrow superconducting nanorings
K. Yu. Arutyunov, T. T. Hongisto, J. S. Lehtinen +2
The smaller the system, typically - the higher is the impact of fluctuations. In narrow superconducting wires sufficiently close to the critical temperature Tc thermal fluctuations…
Quantum phase slip interference device based on superconducting nanowire
T. T. Hongisto, A. B. Zorin
We propose a transistor-like circuit including two serially connected segments of a narrow superconducting nanowire joint by a wider segment with a capacitively coupled gate in bet…
Suppression of diamagnetism in superconducting nanorings by quantum fluctuations
Terhi T. Hongisto, K. Yu. Arutyunov
Zero resistance, diamagnetism (Meissner effect) and the energy gap in the excitation spectrum are the fundamental attributes of superconductivity. In nanoparticles with characteris…
Ion beam shaping and downsizing of nanostructures
M. Zgirski, K. P. Riikonen, V. Tuboltsev +3
We report a new approach for progressive and well-controlled downsizing of nanostructures below the 10 nm scale. Low energetic ion beam (Ar+) is used for gentle surface erosion, pr…
Tunneling spectroscopy of persistent currents in superconducting microrings
K. Yu. Arutyunov, T. T. Hongisto, D. Y. Vodolazov
It is shown that in a structure consisting of a superconducting ring-shaped electrode overlapped by a normal metal contact through a thin oxide barrier, measurements of the tunnel…
