Incoherent tunnelling through two quantum dots with Coulomb interaction
The Ohmic conductance and current through two quantum dots in series is
investigated for the case of incoherent tunnelling. A generalised master
equation is employed to include the discrete nature of the energy levels.
Regions of negative differential conductance can occur in the I-V
characteristics. Transport is dominated by matching energy levels, even when
they do not occur at the charge degeneracy points.Comment: RevTeX + epsf.sty + 13 figure
