Synchronization efiects in intrinsic Josephson junctions by non-equilibrium heating

Shapiro Steps in BSCCO Intrinsic Josephson Junctions

Static Charge Coupling of Intrinsic Josephson Junctions

Since the discovery of the intrinsic Josephson effect not only the typical properties of conventional junctions were demonstrated [1], but also unique and surprising features like the coupling of Josephson oscillations to phonons [2] have been discovered. There has also been a considerable interest in the influence of nonequilibrium effects on the I − V -characteristic and collective modes [3– ...

Dynamical Behaviour of Intrinsic Josephson Junctions

Intrinsic Josephson Junctions (IJJs) are the subject of much of research due to their potential applications as high frequency oscillators and detectors in the THz range. A number of previous studies use a single junction model to explain their observations, as no fully agreed model for coupled IJJs exists. The influence of one or more IJJs in the voltage state on other junctions in the IJJ arr...

Sub-Micron Thin Film Intrinsic Josephson Junctions

We have fabricated sub-micron intrinsic Josephson junctions in thin films of Tl-Ba-Ca-Cu-O using two differing techniques suited to different applications. By using lateral focussed ion-beam milling we have created arrays of intrinsic junctions in -axis oriented films. Such arrays, with areas as low as 0.25 m, display large hysteresis comparable to that observed in single-crystal intrinsic junc...

Phase synchronization in an array of driven Josephson junctions.

We consider an array of N Josephson junctions connected in parallel and explore the condition for chaotic synchronization. It is found that the outer junctions can be synchronized while they remain uncorrelated to the inner ones when an external biasing is applied. The stability of the solution is found out for the outer junctions in the synchronization manifold. Symmetry considerations lead to...
