Nonlocal electrodynamics of long ultra-narrow Josephson junctions: Experiment and theory
A. A. Abdumalikov, V. V. Kurin, C. Helm +3
We experimentally and theoretically investigate electromagnetic cavity modes in ultra-narrow Al-AlO-Al and Nb-AlO-Nb long Josephson junctions. Experiments show that the vol…
Interface steps in field effect devices
S. Wehrli, C. Helm
The charge doped into a semiconductor in a field effect transistor (FET) is generally confined to the interface of the semiconductor. A planar step at the interface causes a potent…
Thermal fluctuations in ultrasmall intrinsic Josephson junctions
A. Franz, Y. Koval, D. Vasyukov +5
Current-voltage curves of small area hysteretic intrinsic Josephson junctions, for which the Josephson energy is of order of thermal energy , are investigate…
Electronic compressibility and charge imbalance relaxation in cuprate superconductors
Ch. Helm, L. N. Bulaevskii, D. A. Ryndyk +5
In the material SmLaSrCuO with alternating intrinsic Josephson junctions we explain theoretically the relative amplitude of the two plasma peaks in transmission…
Field Dependence of the Josephson Plasma Resonance in Layered Superconductors with Alternating Junctions
L. N. Bulaevskii, Ch. Helm
The Josephson plasma resonance in layered superconductors with alternating critical current densities is investigated in a low perpendicular magnetic field. In the vortex solid pha…
Charge-imbalance effects in intrinsic Josephson systems
S. Rother, Y. Koval, P. Muller +4
We report on two types of experiments with intrinsic Josephson systems made from layered superconductors which show clear evidence of nonequilibrium effects: 1. In 2-point measurem…
