摘要
We have investigated experimentally the transport properties of two-dimensional arrays of small tunnel junctions in the charging regime. In such arrays, the random offset charges caused by impurities in the underlying substrate or in the tunnel barriers are expected to strongly affect the conduction. The current through the arrays oscillates periodically with the gate voltage and we have found a linear dependence of the Coulomb voltage gap with the length of the array. These results are a direct measurement of the influence of charge disorder on Coulomb blockade and are in good agreement with theoretical predictions.
