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

β¦ Synopsis
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 oscillations.

Nonlinear electron transport through a semiconductor quantum dot in the low-temperature Kondo regime is studied theoretically. Particular emphasis is put on examining the effects of the inherent multilevel electronic structure of the semiconductor dot. Combining the nonequilibrium Green function met
We have investigated the quantum transport properties of electrons through multiplemagnetic-barrier structures, where the magnetic barriers are created by depositing ferromagnetic stripes on top of a heterostructure. The transmission coefficient and currentdensity-voltage (J -V ) characteristic are
