Abstract
We have measured the current-voltage characteristics of small-capacitance single Josephson junctions at low temperatures (T less than or equal to 0.04 K), where the strength of the coupling between the single junction and the electromagnetic environment was controlled with one-dimensional arrays of dc SQUIDs. When the zero-bias resistance of the SQUID arrays is much higher than the quantum resistance h/e2 approximately equal to 26 kO, a transition to a clear Coulomb blockade of Cooper-pair tunneling is induced in the single junction. The measured blockade voltage agrees with the theoretical prediction.Citation
