High quality Nb/Al-AlOx/Nb Josephson junction

We have improved the quality of Nb/Al-AlOx/Nb Josephson junctions and obtained the most excellent junction characteristics ever obtained for all refractory Josephson junctions. The Vm values (the product of the critical current and the subgap resistance measured at 2 mV) are 88 mV at the critical cu...
