Design and fabrication of 10 V SINIS Josephson arrays for programmable voltage standards

摘要

The fabrication and the chip layout of 69120 SINIS Josephson junction series arrays for a programmable 10 V Josephson dc voltage standard are presented. Under 70 GHz microwave irradiation, the current-voltage characteristic exhibits a non-hysteretic voltage step with a step width of 200 #mu#A. The chip can be operated with the conventional SIS Josephson voltage standard systems.
