The finite temperature I-V-;:haracteristic of a normal tunnel junction coupled to its electromagnetic environment is calculated. It is shown that due to quantum fluctuations of the charge the Coulomb gap is only observable provided the impedance Z(w) of the environment exceeds the resistance quantum

We studied small-capacitance single tunnel junctions with various tunnel resistances. In order to reduce the environmental effect, high-resistance leads were adopted for measurement. We observed the gradual weakening and disappearance of the Coulomb blockade as the tunnel resistance in the absence o
Narrow metal wires patterned on Si(100) wafers by conventional e-beam lithography have been subsequently mechanically modiΓed with an atomic force microscope. Using the line resistance as an indicator of the progress of the modiΓcation, narrow insulating gaps were successfully machined into the line
