| Abstract(in English) | We report on the fabrication and the quasiparticle characteristics for thin film Nb-(Nb nanoconstriction)- NbN short weak links prepared by applying electric field to an insulating Nb, MgO/NbNedge-sandwich with area of 0.2μm^2.The growth of Nb nanoco nstrictions in the MgO(-7nm thick)insulator layer connecting two superconducting banks is assisted by electric field in liquid helium.For an interpretation of device Quasiparticle characteristics,the Blonder,Tinkham and Klapwijk(BTK)theory£Phys.R ev.B25,4515(1982)!is used.The current-voltage curves are found to agree closely with the BTK prediction by assuming two- independent(series)with normal metalsuperconductor contacts. |
