Abstract: By means of modified rate Equations We inVestigate the influence of the transVerse interdot coupling on the AharonoV-Bohm ( AB) structure, Which is composed of two coupled quantum dots ( GDs) sandWiched betWeen source and drain. The numerical results show that the interdot coupling betWeen the two GDs can cause a temporal oscillation in electronoccupation at the initial stage of the quantum dynamics, While the source-drain current decays monotonically to a stationary Value. On the other hand, the interdot coupling diVides the AB ring into two coupled subrings. That destroys the normal AB oscillation and generates a new and complex periodic oscillation With its period related to the magnetic flux ratio.
