โฆ Synopsis
Time correlation of Single Electron Tunneling events i.e. SET-oscillations has been observed in one dimensional arrays of AIIAlxOy/AI tunnel junctions with very small areas (O.006}lm 2 ). They are detected by phase locking to external microwaves with frequency fext between O.7GHz and SGHz. Peaks in the differential resistance occur at currents corresponding to I=efext. Good agreement is obtained with theoretical data.

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
