We have investigated the coupling between CuO 2 layers in high-T c superconductors by
direct measurements of all dc and ac Josephson effects with current flow in the c-axis …

We have investigated Josephson effects in stacks of both artificial and natural Josephson
junctions. The measurements have been performed on Nb/Al-AlO x/Nb multilayers and on …

Characteristic velocities of the electromagnetic waves propagating in vertically stacked
Josephson transmission are theoretically discussed. An equation for solving n velocities of …

Aluminium oxide (AlO x) tunnel junctions are important components in a range of
nanoelectric devices including superconducting qubits where they can be used as …

Static and dynamic properties of stacked Josephson junctions are studied theoretically. An
approximate analytic solution for a stack with arbitrary junction parameters was obtained …

The surface roughness of sputtered Nb films was determined with high precision using x‐ray
specular reflectivity measurements in the 10 keV range. The roughness of Nb films …

A system of two vertically stacked Nb/Al-AlO,/Nb long Josephson junctions is studied
experimentally. The magnetic coupling between the junctions is provided by their common …

The in-phase (rectangular) fluxon lattice is required for achieving coherent THz emission
from stacked Josephson junctions. Unfortunately, it is usually unstable due to mutual …

The microscopic structure of ultra-thin oxide barriers often plays a major role in modern nano-
electronic devices. In the case of superconducting electronic circuits, their operation …

We have studied the microwave response of an array of intrinsic Josephson junctions in the
c-axis direction in large Bi/sub 2/Sr/sub 2/CaCu/sub 2/O/sub 7/(BSCCO) single crystals …
