| Abstract(in English) | Current transport in an series arrays of mesoscopic SNS junctions with very short N-region is described with a resonance tunneling between the SN and NS interfaces, and picture of sequential-tunneling through the cascaded quantum dots. The transport of current in the state of approximating zero voltage is expressed the electron-pair current reflects the multiple-Andreev reflections which quickly decreases in accordance as the bias voltage increase and an I-V characteristic show negative resistance. We developed new process to suppressing the dispersion of the superconducting current Ic and maintaining the value of Ic as the characteristic of series connection at the highest possible. As a result, the voltage range of the negative resistance region (dynamic range) is expanded for each series array of SNS junctions. The SNS junctions are made of all NbN-films. Conductance of the mesoscopic SNS weak-links was sensitively influenced by the critical rf power coupling. |
