Complex phase-fluctuation effects correlated with granularity in superconducting NbN nanofilms
Meenakshi Sharma, Manju Singh, Rajib K. Rakshit +5
Superconducting nanofilms are tunable systems that can host a 3D-2D dimensional crossover, leading to the Berezinskii-Kosterlitz-Thouless (BKT) superconducting transition approachi…
X-ray phase contrast topography to measure the surface stress and bulk strain in a silicon crystal
Enrico Massa, Carlo Paolo Sasso, Matteo Fretto +2
The measurement of the Si lattice parameter by x-ray interferometry assumes the use of strain-free crystals, which might not be true because of intrinsic stresses due to surface re…
Self-organizing memristive nanowire networks with structural plasticity emulate biological neuronal circuits
Gianluca Milano, Giacomo Pedretti, Matteo Fretto +5
Acting as artificial synapses, two-terminal memristive devices are considered fundamental building blocks for the realization of artificial neural networks. Organized into large ar…
Substrate induced proximity effect in superconducting niobium nanofilms
S. J. Rezvani, A. Perali, M. Fretto +5
Structural and superconducting properties of high quality Niobium nanofilms with different thicknesses are investigated on silicon oxide and sapphire substrates. The role played by…
Quantum coherent transport in a three-arm beam splitter and a Braess paradox
E. Zhitlukhina, M. Belogolovskii, N. De Leo +3
The Braess paradox encountered in classical networks is a counterintuitive phenomenon when the flow in a road network can be impeded by adding a new road or, more generally, the ov…
Intrinsically shunted Josephson junctions for electronics applications
M. Belogolovskii, E. Zhitlukhina, V. Lacquaniti +3
Conventional Josephson metal-insulator-metal devices are inherently underdamped and exhibit hysteretic current-voltage response due to a very high subgap resistance compared to tha…
Dimensional crossover and incipient quantum size effects in superconducting niobium nanofilms
N. Pinto, S. J. Rezvani, Andrea Perali +5
Superconducting and normal state properties of sputtered Niobium nanofilms have been systematically investigated, as a function of film thickness in a d=9-90 nm range, on different…
Universality of transport properties of ultra-thin oxide films
V. Lacquaniti, M. Belogolovskii, C. Cassiago +3
We report low-temperature measurements of current-voltage characteristics for highly conductive Nb/Al-AlOx-Nb junctions with thicknesses of the Al interlayer ranging from 40 to 150…
Realization and preliminary measurements on a 94 GHz SIS mixer
L. Oberto, N. De Leo, M. Fretto +3
In this paper we present the realization and a preliminary characterization of a SIS based receiver. It has been developed for the MASTER experiment that consists in a three-band S…
