Abstract(in English) | NbN, AlN/NbN tunnel junctions are fabricated on ambient temperature MgO substrates.A critical current density of 8,000 A/ cm^2 is obtained in junctions with 1.5-nm-thick AlN barriers.The junctions show a large gap voltage(Vg=5 mV),sharp quasipartical current rise(△Vg=0.18 mV)and small subgap leakage current(Vm=20 mV ),even though the NbN/AlN/NbN trilayers are deposited without intentional heating.This report shows that high quality NbN/AlN/ NbN tunnel junctions can be made at ambient substrate temperature. |
