| Abstract(in English) | We fabricated high critical current density Nb, AlOx/Nb tunnel junctions and investigated their characteristics.Subgap excess currett increased with increasing Jc.This degradation of junction quarity is due to the defects of tunnel barrier which is considered to be quite thin for such high Jc junctions.It was found that Jc of the junctions for latching logic gates can be increased up to 10kA/cm^2.Subharmonic gap structure due to Josephson self-coupling was observed and it is shown that pair- quasiparticle interaction is important for characteristics of high Jc junctions. |
