Abstract

The details of electron interference in quantum-dot systems coupled via quantum point contacts (QPCs) is studied via simulation and experiment. In both open and closed coupled systems, one sees transitions from multi- to single-dot behavior, even when the QPCs support several modes. The results also reveal a non-trivial scaling of the conductance fluctuations in quantum-dot arrays, arising from the influence of the inter-dot coupling on energy hybridization.
