Abstract We study the effect of the Coulomb interactions on a charge transport through a single level quantum dot. The excitation spectrum is at low temperatures characterized by a narrow Kondo resonance (the low energy feature) formed on top of the line broadening (high energy part of the spectrum). We investigate mutual interplay between these low and high energy parts and discuss their influence on the transport phenomena for a semi‐equilibrium situation. (© 2007 WILEY‐VCH Verlag GmbH & Co.
