We have calculated the spatial distribution of the electrostatic potential created by an unbalanced charge q in one of the conducting electrodes of a long, uniform, linear array of small tunnel junctions. The distribution describes, in particular, the shape of a topological single‐electron soliton in such an array. An analytical solution obtained for a circular cross‐section model is compared with results of geometrical modeling of a more realistic structure with square cross section. These… 
Charge solitons in closed two-dimensional tunnel junction arrays
Abstract Charge solitons driven by external voltage sources in the two-dimensional array of mesoscopic tunnel junctions which form a closed loop structure are theoretically investigated in this work.
Potential distribution in a finite 1-D array of arbitrary mesoscopic tunnel junctions
Abstract A general expression for the distribution of the potential in a finite one-dimensional array of arbitrary mesoscopic tunnel junctions in terms of Green's function is deduced. It is shown
Coulomb blockade threshold in finite one-dimensional arrays of small tunnel junctions: computer simulation

Additional Coulomb blockade and negative differential conductance in closed two-dimensional tunnel junction arrays
We have theoretically investigated the transport properties of a two-dimensional array of small tunnel junctions having two different paths between the source and the drain electrodes. We have found
Electronic correlations and disorder in transport through one-dimensional nanoparticle arrays
We report on a detailed study of the transport properties of one-dimensional metallic nanoparticle arrays, which focuses on threshold voltages and on the spatial distribution of potential drops
Kinetic Inductance and Coulomb Blockade in One Dimensional Josephson Junction Arrays
One dimensional Josephson junction arrays have been fabricated andcurrent-voltage characteristics (IVC) have been measured at cryogenic temperatures. The arrays were fabricated in a SQUID-geometry
Single-electron tunnelling devices based on intrinsic Josephson junctions in Bi-2212
We fabricated submicron-sized intrinsic Josephson junctions of Bi-2212 by the focused-ion-beam (FIB) etching method. The main result was a reduction of the in-plane junction area to 0.3 µm2 by direct
Intrinsic Josephson effect and single Cooper pair tunneling
Abstract We proposed a new, small and fast switching gate based on the intrinsic Josephson effect of single crystals of a cuprate superconductor. The switching time is of subpicosecond order, and the
Fabrication of single electron tunneling devices using layered structures of high-Tc superconducting materials
Abstract We have fabricated the submicron structures using high- T c superconducting materials of Bi 2 Sr 2 CuO 6+ δ (Bi-2201). The stacks of layered structures are made by focused-ion-beam (FIB)
Nanometer range: A new theoretical challenge for microelectronics and optoelectronics
TLDR
Re Revisiting the method of space-time domain paves the way to a new era of developments, by considering that a trapped particle located in a bounded bi-dimensional space, having less than 1 eV of kinetic energy, should have an associated wavelength representing a fraction of a wave cycle.
