Abstract

Description

We study the electronic transport through a quantum wire (QW) with a strong side coupled quantum dot (QD). We obtain a linear conductance with lateral peaks when the gate voltage, is located near the edge of the conduction band. The calculated density of states shows, that these peaks are associated with renormalized localized levels out side of the conduction band. These results are compatibles with recent experimental results.
