One-Dimensional Arrays of Small Tunnel Junctions
Several of the characteristic and interesting single charge tunneling effects have been observed in ID arrays of tunnel junctions, i. e., in series coupled arrays of many, closely spaced, ultrasmall junctions. For example, the time correlation of tunnel events was first observed in such an array. The interpretation of the results obtained with an array may be complicated as compared to a single junction, but the additional degrees of freedom for an array, like the formation of charge “solitons”, may be of advantage in developing the single charge effects and, in particular, for applications of these effects. One of the advantages of series coupled junctions is that it is easier to fabricate high resistance tunnel junctions closely connected to the junction under study than high resistance conventional resistors.
