Critical voltage of a mesoscopic superconductor.
We study the influence of a voltage-driven nonequilibrium of quasiparticles on the properties of short mesoscopic superconducting wires. We employ a numerical calculation based upon the Usadel equation. Going beyond linear response, we find a nonthermal energy distribution of the quasiparticles caused by the applied bias voltage. It is demonstrated that this nonequilibrium drives the system fro...
متن کاملDistinct doping dependence of critical temperature and critical current density in Ba1−xKxFe2As2 superconductor
Since the high transition temperature (High-Tc) superconductivity was discovered in the series of materials containing iron (Fe), their potential for the applications has been extensively scrutinized. In particular, a lot of effort has been made in achieving the high current-carrying ability by revealing the vortex pinning behavior. Here, we report on the critical current density (Jc) for the p...
متن کاملHigh critical-current superconductor-InAs nanowire-superconductor junctions.
We report on the fabrication of InAs nanowires coupled to superconducting leads with high critical current and widely tunable conductance. We implemented a double lift-off nanofabrication method to get very short nanowire devices with Ohmic contacts. We observe very high critical currents of up to 800 nA in a wire with a diameter of 80 nm. The current-voltage characteristics of longer and suspe...
متن کاملBiotemplated synthesis of an ordered macroporous superconductor with high critical current density using a cuttlebone template.
Periodic superconducting, porous self-supporting monoliths were synthesized using cuttlebone as a morphological template; this produced a lightweight, structurally stable superconductor with a greatly improved critical current density.
متن کاملDepairing currents in the superconductor/ferromagnet proximity system Nb/Fe
We have investigated the behaviour of the depairing current Jdp in ferromagnet/superconductor/ferromagnet (F/S/F) trilayers as function of the thickness ds of the superconducting layers. Theoretically, Jdp depends on the superconducting order parameter or the pair density function, which is not homogeneous across the film due to the proximity effect. We use a proximity effect model with two par...
