Tunneling transport through multi-electrons states in coupled quantum dots with Coulomb correlations
arXiv:1407.0575 · doi:10.1016/j.ssc.2014.09.002
Abstract
We investigated the peculiarities of non-equilibrium charge configurations in the system of two strongly coupled quantum dots (QDs) weakly connected to the reservoirs in the presence of Coulomb correlations. We revealed that total electron occupation demonstrates in some cases significant decreasing with increasing of applied bias - contrary to the situation when Coulomb correlations are absent and found well pronounced ranges of system parameters where negative tunneling conductivity appears due to the Coulomb correlations.
