| Abstract(in English) | We studied the spread of the critical current (I_c) for Nb-AlOx-Nb Josephson junctions. Room temperature measurements for the junction resistance gave the reasonable dependence of the JJ area. Low temperature measurements of IV characteristics for serial JJ arrays gave the I_c spreads consisting of two components, one is the JJ area component and the other is originated from the noise of the measurement system and test circuits. We proposed the model explaining the noise-origin I_c spread. Estimation based on the model showed good agreement with the measured JJ-size dependence. |
