Abstract
We report our study of I-V curves in the transport through the quantum dot when an additional quantum dot lying in the Kondo regime is side-connected to it. Due to the Kondo scattering of the effective spin on a side-connecte d quantum dot, the conductance is suppressed at low temperatures and at low source-drain bias voltages. This zero-bias anomaly is understood as enhanc ed Kondo scattering with decreasing temperature.
