In this work we introduce a simple phe-
nomenological model of the conduction between
a couple of serial or parallel quantum dots. This
model is extended to an arbitrary of number and
to a square array of quantum dots. The local
potential is computed taking into account the net
charge at the quantum dot. Master equations are
presented for total current and charge number N
considering both the local potential and the local
current. Interesting results are reported, namely
the Negative Di erential Resistance for serial
quantum dots as well as resonant conductance. A
paradoxical asymmetric current appears for the
parallel case due to the capacitive coupling.
