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...
متن کاملNonlinear response of a thin metamaterial film containing Josephson junctions
An interaction of electromagnetic field with metamaterial thin film containing split-ring resonators with Josephson junctions is considered. It is shown that dynamical self-inductance in a split rings results in reduction of magnetic flux through a ring and this reduction is proportional to a time derivative of split ring magnetization. Evolution of thin film magnetization taking into account d...
متن کاملEffect of current injection into thin-film Josephson junctions
New thin-film Josephson junctions have recently been tested in which the current injected into one of the junction banks governs Josephson phenomena. One thus can continuously manage the phase distribution at the junction by changing the injected current. A method of calculating the distribution of injected currents is proposed for a half-infinite thin-film strip with source-sink points at arbi...
متن کاملStatic 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– ...
متن کاملDynamical 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...
