Making use of the equation of motion method and Keldysh Green function technique, we obtain a general current formula for a quantum-dot-ring with one of the dots connected to two electron reservoirs under a DC bias voltage. The transmission probability TΓ°oΓ as a function of electron o curve is prese
We investigate anti-resonances in the conductance of a ferromagnetic lead with a side-coupled quantum dot resulting from interference between a resonant and a nonresonant path through the system. The transport properties of electrons are derived in Coulomb blockade regime by the use of the equivalen
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
