Non-coherent transport in serial/parallel quantum dots in self-consistent eld regime

Abstract

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.
