摘要：

We describe an experiment in which we attached high- and low-resistance thin film leads to normal metal tunnel junctions with capacitances of order 10-15 F. At 20 mK we observed a pronounced Coulomb blockade in the former case, and a very smeared blockade in the latter case. We outline a model which indicates that the low temperature behavior of the junctions is dominated by quantum fluctuations in the external circuit. The predictions of the model are in fairly good agreement with the observed current-voltage characteristics. © 1990, Elsevier Science Publishers B.V. (North-Holland). All rights reserved.
