Abstract(in English) | Submicron NbN bridges whose thickness,width and length are 10nm, 100nm and 100-300nm respectively,have been fabricated,and their conduction properties and electrical field effects are measured. The samples having resistances larger than~100kΩ exhibit nonlinea r I-V characteristics with offset voltage of 2mV~12mV at low tempe ratures which are obviously similar to those of the single- electron charging effect in small tunnel junction arrays.The field effect modulation of the junction conductance is observed by applying a voltage to a gate electrode which is made over the NbN bridge.These charging effects are thought to arise from the granular structure of NbN bridges.The simulation results using one- dimensional SET junction arrays coincide well with experimental results. |
