External ﬁeld induced switching of tunneling current in the coupled quantum dots
We investigated the tunneling cureent peculiarities in the system of two coupled by means of the external ﬁeld quantum dots (QDs) weakly connected to the electrodes in the presence of Cou lomb correlations. It was found that tuning of the Rabi frequency induces fast multiple tunneling current switching and leads to the negative tunneling conductivity. Special role of multi- electrons states was demonstrated . Moreover we revealed conditions for bistable behavior of the tunneling current in the coupled QDs with Coulomb correlations.
