Superconducting insulators and localization of Cooper pairs
Konstantin Yu. Arutyunov, Janne S. Lehtinen, Alexey Radkevich +2
Rapid miniaturization of electronic devices and circuits demands profound understanding of fluctuation phenomena at the nanoscale. Superconducting nanowires -- serving as important…
Thermal relaxation in titanium nanowires: signatures of inelastic electron-boundary scattering in heat transfer
Teemu Elo, Pasi Lähteenmäki, Dmitri Golubev +3
We have employed noise thermometry for investigations of thermal relaxation between the electrons and the substrate in nanowires patterned from 40-nm-thick titanium film on top of…
Quantum size phenomena in single-crystalline bismuth nanostructures
Egor A. Sedov, Kari-Pekka Riikonen, Konstantin Yu. Arutyunov
Size-dependent quantization of energy spectrum of conducting electrons in solids leads to oscillating dependence of electronic properties on corresponding dimension(s). In conventi…
The quantum phase slip phenomenon in superconducting nanowires with high-impedance environment
K. Yu. Arutyunov, J. S. Lehtinen, T. Rantala
Quantum phase slip (QPS) is the particular manifestation of quantum fluctuations of the order parameter of a current-biased quasi-1D superconductor. The QPS event(s) can be conside…
Quasi-1-Dimensional Superconductivity in Highly Disordered NbN Nanowires
K. Yu. Arutyunov, A. Ramos-Álvarez, A. V. Semenov +6
The topic of superconductivity in strongly disordered materials has attracted a significant attention. In particular vivid debates are related to the subject of intrinsic spatial i…
Junctionless Cooper pair transistor
K. Yu. Arutyunov, J. S. Lehtinen
Quantum phase slip (QPS) is the topological singularity of the complex order parameter of a quasi-one-dimensional superconductor: momentary zeroing of the modulus and simultaneous…
