Abstract

The details of electron interference in open quantum-dot arrays are studied in experiment and numerical simulations. Reproducible fluctuations are observed in their low-temperature magnetoconductance and the characteristics of these are suggested to be consistent with a transition from multiple to single-dot interference, which occurs as the strength of the interdot coupling is varied. These results therefore reveal a nontrivial scaling of the conductance fluctuations in quantum-dot arrays, which is thought to arise due to the influence of the interdot coupling on energy hybridization.
