| 英文摘要 | We have studied the current-voltage properties of a double quantum dot (dqd) connected by leads in arrangements that vary from series to symmetrical parallel configurations, in the presence of strong intradot coulomb interaction. the influences of the connecting configurations and the difference between dot levels on the magnitude and symmetry of the total current are examined. we find that the connecting configurations of the dots can determine the number of the current paths and in turn determine the magnitude of the current, while the coupling strengths between the dots and the leads together with the difference of dot levels determine the current-voltage symmetry. the negative differential conductance observed in serial dqd can be explained in terms of the reduction of the current paths.
