In this paper we review our recent study of coherent electronic properties of coupled twodimensional quantum dot arrays using numerical exact-diagonalization methods on a Mott-Hubbard type correlated tight-binding model. We predict the existence of a novel kind of persistent current in a two-dimensi
The magnetoresistance of electrons in a two-dimensional array of dots has been investigated. The new commensurability oscillations were found when \(2 \mathrm{R}_{L}=\mathrm{d}\) and \(2 R_{L}=\mathrm{d} / 2\). The closed electron trajectories skipping inside the dot are responsible for these oscill
