概要
- 論文の詳細を見る
In this report, we describe an experimental study of the quantized electrical field effect in granular superconductor thin films which are regarded as two-dimensional arrays of small superconductor junctions. The periodic variation of the film conductance appears with the induction of a pair electron charge on each grain. The maximum variation ratio of the experimentally observed film resistance is about 40%. Besides the periodic field effect, the reproducible aperiodic conductance variation is also observed. These periodic and aperiodic field effects are explainable supposing the presence of intergrain junctions with phase quantum tunneling (PQT) behavior which is dual to the Josephson effect.
