Control of Coulomb blockade in a mesoscopic Josephson junction using single electron tunneling
نویسندگان
چکیده
We study a circuit where a mesoscopic Josephson junction ~JJ! is embedded in an environment consisting of a large bias resistor and a normal-insulator-superconductor ~NIS! junction. The effective Coulomb blockade of the JJ can be controlled by the tunneling current through the NIS junction leading to transistor-like characteristics. We show using phase correlation theory and numerical simulations that substantial current gain with low current noise (in&1 fA/AHz) and noise temperature ~&0.1 K! can be achieved. Good agreement between our numerical simulations and experimental results is obtained. © 2004 American Institute of Physics. @DOI: 10.1063/1.1751231#

متن کاملMesoscopic Josephson Effect
In the classical Josephson effect the phase difference across the junction is well defined, and the supercurrent is reduced only weakly by phase diffusion. For mesoscopic junctions with small capacitance the phase undergoes large quantum fluctuations, and the current is also decreased by Coulomb blockade effects. We discuss the behavior of the current-voltage characteristics in a large range of...
متن کاملCoulomb blockade and coherent single-cooper-pair tunneling in single Josephson junctions.
We have measured the current-voltage characteristics of small-capacitance single Josephson junctions at low temperatures ( T< or =0.04 K), where the strength of the coupling between the single junction and the electromagnetic environment was controlled with one-dimensional arrays of dc SQUIDs. We have clearly observed Coulomb blockade of Cooper-pair tunneling and even a region of negative diffe...

متن کاملRoom Temperature Hydrogen Sensor Based on Single-Electron Tunneling Between Palladium Nanoparticles
In this paper, we present the results of single-electron tunneling in two-dimensional (2D) hexagonal closed packed arrays of palladium nanoparticles. After inspecting the emergence of Coulomb blockade phenomena, we demonstrate the possibilities of using these arrays as a single-electron tunneling based hydrogen sensor. We assumed arrays of palladium nanoparticles with diameters of 3.5 and 6...
